Solutions

Expert Solution

Answer : c) 0.015 s-1

Explanation :

Given :

[A] = 0.75 M,  k= 0.02

Reaction :  A + H2O → products

For pseudo first order reaction rate equation is R = k [A].

The reaction is  pseudo first order reaction based on the unit is s-1. 

The formula to calculate the rate of pseudo first order reaction is given by,

R = k [A]

   = 0.02 × 0.75

   = 0.015 s-1.

c) 0.015 s-1
