Question

If a zero order reaction completed to 60% in 30 minutes then time in which reaction completed to 80% will be

Answer 1

Answer:

40 minutes

Explanation:

Let initial reactant conc. be x.

Then,

so,

0.6x = -k*t_1

and

0.8x = -k*t_2

Dividing these two equations,

3/4 = t_1/t_2

t_2 = 4*30/3 = 40 minutes
