k

Postby Diana_Diep2I » Sat Mar 14, 2020 9:46 am

Does the value of k affect the rate of a reaction? Like if k is large, does it mean that the rate of reaction is faster?

if concentration is kept constant, then yes, a larger k results in a faster rate

A larger K does indicate a faster reaction.

Yes, usually a larger k results in a faster rate of reaction

k is the rate constant, and is used in the differential rate law. Yes, if k is higher, then the rate of reaction will be higher, meaning the rate will be faster.

Since k is the rate constant, if everything else is constant, if you increase the value of k, the reaction rate will increase.

large k indicates a fast rate and a small k indications a slow rate

The opposite applies to half lives, a larger k means a shorter half life.

If k, the rate constant, is larger value, then the reaction rate is faster.

In an overall rate law, the concentrations will all be constant, so yes, the value of k will determine the speed of the reaction. Thus, a larger k will most definitely result in a faster reaction rate as opposed to a very small k value.

Yes you have the correct reasoning. The larger the value of k the faster the reaction.

Yes, exactly. A larger k value will cause the reaction to be faster as long as concentration is constant.

k is the reaction constant (calculated using experimental data). rate=k*[R]^n (n=order of reaction). Yes, as k increase, rate will increase.

Yes, a larger k represents a higher rate of the reaction. This is because the rate=k*[R]^n.

Yes, a large k means a fast rate of reaction. K is the rate constant, so this logically makes sense. Hope this helped!

Hi, the larger the value of K, the reaction rate will be faster whereas a smaller value of K will be a slower rate. Hope this helps!

Yes, the specific rate constant k is the proportionality constant relating the rate of reaction to the concentration of reactants. A large value means the rate is relatively fast, while a small value means it is relatively slow.

A larger k does mean a faster reaction rate. Since rate=k[R]^n, larger k, larger rate.

Yes a larger k means a larger rate constant which means that the reaction is occurring faster.

From my understanding, yes, a larger k value has the ability to make a reaction faster as long as the concentration is constant.

as everyone is saying, yes a larger K makes for a faster reaction as long as pressure is constant.

The magnitude of the equilibrium constant, K, indicates the extent to which a reaction will proceed: If K is a large number, it means that the equilibrium concentration of the products is large. In this case, the reaction as written will proceed to the right (resulting in an increase in the concentration of products).

Hi,

if everything else is kept constant in the equation, then if k is large then yes, the rate of the reaction is faster.

As long as the concentration is kept constant, then you are correct in saying that a larger k will result in a faster rate

Correct! Since rate=k*[R]^n, the rate constant (k) and the rate of the reaction are directly proportional! As the value of k increases, the rate of reaction increases.

A larger k means the reaction is going to happen faster. A smaller k means the reaction is going to happen slower. This is only true if the concentration is constant.

The larger the k value, the faster the reaction and vice versa. The smaller the k value, the slower the reaction is

rate constant is part of the rate equation, so yes, if rate constant is larger, the rate will also be larger (faster).

Yes, since k is the rate constant we know that the rate of the reaction will be higher if the k is larger.
