exercise 15.65

Postby 505166714 » Thu Mar 14, 2019 1:58 pm

In this question, the equilibrium of the reaction is K=[B][C]/[A]^2
Should we consider the reaction order when calculating the equilibrium constant using rate constant?
Doesn't [A]^2 means the order of reaction for A is two? Why can we directly plug in the rate constants provided regardless of the reaction order?

The equilibrium constant is defined as k/k', which is forward rate / reverse rate. The problem already gives you the rates, which already took into account the order with respect to reactants or products.
