A closed, rigid tank fitted with a paddle wheel contains 0.1 kg of air, initially at 300 K, 0.1 MPa. The paddle wheel stirs the air for 20 minutes, with the power input varying with time accordingto W = -10t, where W is in watts and t is time, in minutes. The final temperature of the air is 1060K. Assuming ideal gas behavior and no change is kinetic or potential energy, determine for the air(a) the final pressure, in MPa, (b) the work, in kJ, and (c) the heat transfer, in kJ.

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.
