Question

The half life of a first order reaction is 900 min at 820 K. Estimate its half life at 720 K if the energy of activation of the reaction is 250 kJ mol⁻¹.

Answer 1

The formula,

Ki = A * e^-E/RT is used for the analyses,

Here all the values will be same except the temperature and the activation number.

First, we need to calculate the total time taken up for the second part. For that, the ratio of the equation will be kept to calculate the answer.
