3. 70 kJ/mol                                       

4. 100 kJ/mol

A first-order reaction takes 40 min for 30 % decomposition. The t_1/2 for this reaction will be:

The half-life period for a first-order reaction is 20 minutes. The time required to change the concentration of the reactants from 0.08 M to 0.01 M will be:
