Organic Chemistry Unit 3: Energy

Standard conditions are 100 kPa, which is 1 atmospheres and 298K, which is 25°C although in liquids it is a concentration of 1 mol dm-3

The equation for the complete combustion of methane is CH4(g) + 1.5O2(g) -->CO(g) + 2H2O(l)

The energy from photosynthesis comes from the light of the sun

Activation energy is the minimum energy required to start a reaction by the breaking of bonds.

When a liquid the standard conditions are a concentration of 2.0 mol dm-3

In Q=mcΔT, c is the specific heat capacity of the surroundings

Bond enthalpy is the enthalpy change that takes place when breaking by homolytic fission 1 mol of a given bond in the molecules of a gaseous species

Hess's law states that if a reaction can take place by more than one route and the initial and final conditions are the same, the total enthalpy change is the same for each route

When one of the reactants has been used up the reaction continues

A catalyst slows down a reaction and is used up in the process
