1.) The reaction A (aq)-->B (aq) is a first order reaction where the haf life of A (aq) of the reaction at 25 degrees celsius is 377 seconds. The half life of the reaction at 35 degrees celsius is 333 s. What is the necessary time for the concentration of A (aq) to fall from 0.777 M to 0.222 M at 50 degrees celsius? The answer is 507 seconds?

2.) THe N2O (g) decomposes to give N2 (g) and O2 (g). The reaction is a first order reaction for N2O (g). If we start with N2O (g) in the container with a fixed temperature and volume and the pressure is 10.00 atm, what is the total pressure after a half life? The answer is 12.50 atm?
