Question

The rate constant of a zero order reaction is 0.02 mol/Ls . What is the time required for the conversion of 10 mol of the reactants into 5.2 moles?

Answer 1

Answer:

Time required is 240 seconds.

Explanation:

Integrated rate law for a zero order reaction is given by :

[A] = [A]. - kt

Here [A] = 5.2 mol

        [A]. = 10 mol

         k = 0.02 mol/L sec

Using above formula

5.2 = 10 - 0.02 t

5.2 - 10 = - 0.02 t

- 4.8 = - 0.02 t

t = 4.8/0.02

t = 480/2

t = 240 seconds

Hope the solution is clear to you. :)
