WebIf one of the factors is halved, the volume produced will be half as much. If the factor is doubled, the reaction will produce double the volume. This applies to all factors that can … WebThe magnitude of ΔH is dependent upon the amounts of reactants consumed. Doubling the reactants, doubles the amount of enthalpy. 2.Reversing a chemical reaction results in the same magnitude of enthalpy but of the opposite sign. 3.The enthalpy change for a reaction depends upon the state of the reactants and products.

http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch3/equations.html WebMost of the chemical reactions show a change in their reaction rate with varying temperature. It has been observed that the rate constant for a chemical reaction gets doubled for every 10 o C rise in temperature. Until 1889, there was no fixed way to physically measure the temperature dependence of the rate of a chemical reaction. bitbucket account password
