Modern wind turbines generate electricity from wind power. the large, massive blades have a large moment of inertia and carry a great amount of angular momentum when rotating. a wind turbine has a total of 3 blades. each blade has a mass of m = 5500 kg distributed uniformly along its length and extends a distance r = 48 m from the center of rotation. the turbine rotates with a frequency of f = 15 rpm.

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.
