Units for t
What are the correct units for t? The solutions manual leaves it in minutes but aren't the correct units in seconds?

Re: Units for t
Time is generally written as seconds (as the standard SI unit); however, it can be represented as minutes or hours depending on the duration of the reaction. If you do happen to change time from seconds to minutes or from hours to minutes and so on, remember to change the value and units of your "k" value so that the units at the end match up.

Re: Units for t
You can use whichever units you would like but, as Brian said, make sure the units match up in all of your terms before solving.

Re: Units for t
It easiest if you change the t value to the time value of your rate constant. In this way you can easily multiply and get the right answer without changing the rate constant units.

Re: Units for t
t can be in seconds, minutes, or hours, but MUST be consistent across all terms or it will mess up your calculations.

Re: Units for t
i think it depends on what the problem asks for. most times in calculations it is seconds
Re: Units for t
T can be in either seconds, minutes, or hours depending on what the problem asks for. As before mentioned the same units must be used throughout the problem.
Re: Units for t
t can be in any unit of time depending on what is asked in the problem. Seconds is generally used because it is the SI unit we have associated with time. Just make sure that your units cancel and that the math makes sense.

Re: Units for t
Just to ensure I didn't mix up anything I usually convert everything to seconds before trying to solve the problem - if it asks to be expressed in minutes or hours you can convert back at the end.

Re: Units for t
It usually just depends on the units of the information you were given in the problem. I'm pretty sure you won't be marked wrong if you leave your t in either minutes or seconds (or even hour) as it is the correct number of sec/min/hr. I hope this helped!

Re: Units for t
It honestly depends on the context of the question, but I use seconds because it is the SI unit. It also depends on your k.

Re: Units for t
i don't think it matters as long as it's consistent throughout all the calculations and everything. I usually use seconds.

Re: Units for t
t is mostly in seconds, however, it can be in minutes or hours. Just make sure that all your units match up across the formula - if you're doing minutes or hours, make sure that the others are relative to that as well.

Re: Units for t
It really depends on the reaction and how long it takes. But seconds is a standard unit.

Re: Units for t
T is usually measured in s, especially for rate reactions because they tend to be very quick. For half-lives, it's usually measured in hours. Generally though, it doesn't matter which units you use as long as you convert everything to match that unit.

Re: Units for t
The SI unit for time is seconds (symbol: s), however, we don't always work in SI units and may be asked for answers in terms of minutes or hours, which we can convert to using stoichiometry. Just make sure your units cancel out!

Re: Units for t
As long as the unit is consistent across your calculations and matches the answer choice, it is okay to use anything. Technically, the SI unit for time is seconds so that is probably preferred or used most often.

Re: Units for t
The tesla (symbolized T) is the standard unit of magnetic flux density. It is equivalent to one weber per meter squared (1 Wb · m -2 ). Reduced to base units in the International System of Units ( SI ), 1 T represents one kilogram per second squared per ampere (kg · s -2 · A -1 ).

Re: Units for t
Hi,
The standard unit of time is seconds, but usually, the common rule of thumb is just to make sure that your units match up with the units of the answer/values given.

Re: Units for t
Hello,
t can be in whatever unit you would like it to be second, mins, hours, just as long as the t unit is consistent for all values.
Hope this helps.

Re: Units for t
seconds is standard, I recommend doing all calculations in seconds before any conversions needed for a specific problem.

Re: Units for t
t, when it is referring to time, can be seconds, minutes, or hours. Just make sure the units are consistent in your calculations.

Re: Units for t
t refers to time. It can be given in seconds, minutes, hours, etc. Just make sure that your units match/cancel out in your equations.
Re: Units for t
as t refers to time it does not matter whether you choose sec, min, or h as long as you match it up with the rest of the problem

Re: Units for t
t represents time and can have different units depending on what the problem asks. I believe the standard unit is seconds, but make sure the units work out with any equations you are using.
