Enthalpy
... The molecules in a solid are vibrating in place. Temperature is a measure of the average kinetic energy that the molecules. As the temperature rises, more kinetic energy is added and the molecules vibrate more. At one particular temperature, the molecules begin to tumble past each other. This breaki ...

... The conversion of graphite to carbon requires enormous pressure and high temperature. Other processes would be dangerous: the decomposition of an explosive like nitroglycerine or diazomethane. The diborane example showed how it is possible to calculate enthalpies from other reactions which can be st ...

... In order for a reaction to occur, the reactant particles must physically collide with each other In this case, 2 C2H2’s and 5 O2’s would need to collide in the same place at the same time VERY UNLIKELY * OK, so how does this work then? The chemical reaction is divided into a series of steps, each of ...
