InterviewSolution

1.	A first-order reaction Ato B , requires activation energy of 70 kJ "mole"^(-1) . When a 20% solution of A was kept at 25^@C for 20 minutes, 25% decomposition took place. What will be the per cent decomposition in the same time in a 30% solution maintained at 40^@C ? Assume that activation energy remains constant in this range of temperature.
Answer» SOLUTION : First calculate `k_25`, then `k_49`. Again find out per cent DECOMPOSITION at `40^@C` 67.17%
