Units of Rate Constant - Full Table
Reaction Order Rate Law Units of Rate Constant (k)
Zero Order r=k M*s^(-1) (mol*L^(-1)*s^(-1))
First Order r = k[A] s^(-1)
Second Order r = k[A]^2 or k[A][B] M^(-1)*s^(-1) (L*mol^(-1)*s^(-1))
Third Order r = k[A]^3 or k[A]^2[B] M^(-2)*s^(-1) (L^2*mol^(-2)*s^(-1))
nth Order r = k[A]^n M^(1-n)*s^(-1) (L^(n-1)*mol^(1-n)*s^(-1))
