Question

HELP! I NEED THIS ANSWERED ASAP!!!

The reaction
A + 2B + C --> Products has a rate law of Rate = k[A]^2[B].
By what factor would the reaction rate change if [C] is tripled?

Answer 1

The rate of reaction will maintain constant

Step-by-step explanation:

Rate of reaction is proportionate to rate constant x [A] ^2 x [B]. This means that the order of reaction with respect to C is 0 as it does not affect the rate of reaction as seen in the rate equation.

Essentially, order of reaction with respect to C is [C] ^0

Hence if [C] triples and becomes [3C]^0, the result will still be 1 as anything to the power of 0 is 1.

Therefore, the answer is that the rate of reaction will remain constant.
