Steel is very stiff, and Young's modulus for steel is unusually large, 2 x 1011 N/m2. A cube of steel 17 cm on a side supports a load of 80 kg that has the same horizontal cross section as the steel cube. (a) What is the magnitude of the "normal" force that the steel cube exerts on the load? (b) What is the compression of the steel cube? That is, what is the small change in height of the steel cube due to the load it supports? Give your answer as a positive number. lcompression| The compression of a wide, stiff support can be extremely small

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.
