A first order reaction A rarr B requires...

A first order reaction `A rarr B` requires activation energy of `70 kJ mol^(-1)`. When a `20%` solution of `A` was kept at `25^(@)C` for `20 min`, `25%` decompoistion took place. What will be the percentage decompoistion in the same time in a `30%` solution maintained at `40^(@)C` ? (Assume that activation energy remanis constant in this range of temperature)
