The rate constant of a reaction : 8.3 x 10⁻⁴

Further explanation

Given

rate = 1 x 10⁻² (mol/L)/s, [A] is 2 M, [B] is 3 M, m = 2, and n = 1

Required

the rate constant

Solution

For aA + bB ⇒ C + D

Reaction rate can be formulated:


\large{\boxed{\boxed{\bold{r~=~k.[A]^a[B]^b}}}

the rate constant : k =


\tt k=(rate)/([A]^m[B]^n)\\\\k=(1.10^(-2))/(2^2* 3^1)\\\\k=8.3* 10^(-4)
