The gas phase reaction A→B+2C is carried out in a constant volume batch reactor (V=25 L). Twenty moles of A with 80% purity (the remainder is inert) are introduced into the reactor. Calculate the time to reduce the concentration of A to 0.1 mol/L if the reaction is first order with k=0.524 min-1. Calculate the time required to consume 10 mols of A if the reaction is second order and k=0.982 L/mol.h. If the temperature is 150°C, what is the total initial pressure? What is the final total pressure if the reaction occurs in its entirety? Explain why pressure varies in this situation.

The gas phase reaction A→B+2C is carried out in a constant volume batch reactor (V=25 L). Twenty moles of A with 80% purity (the remainder is inert) are introduced into the reactor.
Calculate the time to reduce the concentration of A to 0.1 mol/L if the reaction is first order with k=0.524 min-1.
Calculate the time required to consume 10 mols of A if the reaction is second order and k=0.982 L/mol.h.
If the temperature is 150°C, what is the total initial pressure? What is the final total pressure if the reaction occurs in its entirety? Explain why pressure varies in this situation.
