It is necessary to determine the specific heat of an unknown object. the mass of the object is measured to be 199.0 g. it is determined experimentally that it takes 16.0 j to raise the temperature 10.0°c. find the specific heat of the object.

Molten iron fills a mould, which has a volume of 200 cm cubed. calculate the volume when the iron cools and solidifies.

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.
