integrated rate law vs general

[connie 2C]

what’s the difference between the integrated rate laws vs the general rate law?

[Bilal Pandit 1J]

The integrated rate law is the result of integrating the general rate law, to give you the exact concentration of a reactant at a certain time.

[Justin Quan 4I]

To add on, the general rate law is a differential equation that describes the change in concentration of reactant over change in time. By using calculus, you can integrate the general rate laws to get an integrated rate equation that relates concentrations with time directly.

[Jasmine Fendi 1D]

I think that the general rate law gives you the rate while the integrated rate laws gives the concentration of the reactants.

What is each one used for?

Integrated rate law is the rate within a time period so you can see the rate at that time, but the general rate law is just the rate vs the conc. of reactants.

what’s the difference between the integrated rate laws vs the general rate law?

think of driving in a car (this is example used in textbook).
general rate law is like saying you took an hour trip, and ended up driving 30 miles. your average (general) speed for the entire hour time period is 30 mph.
BUT lets say in order to get around a road obstruction, you had to slow down for a small stretch on the road. In that instant (integrated rate law), you were going 20 mph.

when do you know which to use?

When they ask for the rate at a certain time you should use the integrated rate law
