At 380oC, the half-life period for the first order decomposition of H2O2 is 360 min. Calculate the time required for 75% decomposition at 450oC.

A first order reaction A \(\to\) B, requires activation energy of 70 kJ mol-1. When 20% solution of A was kept at 25oC for 20 minutes, 25% decomposition tooks place. What will be the percentage decomposition in the same time in a 30% soluti...

The decomposition of N2O5 according to the equation:
2N2O5 (g) \(\to\) 4NO2(g) + O2(g)
is a first order reaction. After 30 min. from the start of the decomposition in a closed vessel, the total pressure developed is found to be 284.5 mm of ...
