(5) The gas phase non-elementary irreversible reaction oecurs in a batch reactor at constant pressure and temperature. The rate equation of this reaction can be expressed by the following expression: AB+Cr=kC0.5 The reactor contains only pure species at the beginning of the reaction. The pressure and temperature of the reactor are constant values of 2atm and 150C, respectively. The volume of the reactor reaches 1.5 times its initial volume after 12.6 minutes. Find the constant rate of the reaction. Once again, this reaction takes place in a constant-volume batch reactor at 150C. This time the reactor is filled with a gas mixture (60%,30%B, and 10% Inert) at an initial pressure of 2atm. Calculate the total pressure of the reactor after 5 minutes
