A ball is thrown straight up from the roof of an 80-foot building and it's height is modeled by the h(t) = −12t2 + 48t + 80, where h is the height in feet and t is time in seconds. How long (in sec) will it take the ball to hit the roof of the building on its way down? That is, solve h(t) = 80.

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.
