Question

a second order reaction in which the initial content ration of both the reactants are same is 25% complete in 600 seconds .how long will it take for the reaction to go to 75%.completion

Answer 1

Explanation:

The second order equation when both the reactants have same concentration is

k=t1⋅a(a−x)x

If a=100,   x=20,  t=500 seconds.

So, k=5001×100×(100−20)20

When a=100,  x=60,  t=?

          t=k1⋅100×4060

Substituting the value of k,

t=20500×100×80×100×4060

or t=3000 seconds
