WebRearranging the rate equation, the value of the rate constant ‘k’ is given by: k = Rate/ [A] x [B] y. Therefore, the units of k (assuming that concentration is represented in mol L -1 or M and time is represented in seconds) can be calculated via the following equation. k = (M s-1)* (M-n) = M(1-n) s-1. The units of the rate constants for ... WebFeb 12, 2024 · The rate law is as follows: r a t e = k [ A] x [ B] y. where. [A] is the concentration of species A, x is the order with respect to species A. [B] is the concentration of species B, y is the order with respect to species B. k is the rate constant. n is the reaction order for the whole chemical reaction.
