A2 Chemistry Equilibrium (Kc Kp and the reaction quotient) (Topic 11 Edexcel 2015 Specification)

The PowerPoint provides examples in how to calculate Kc and Kp.

More detail is now assessed in relation to the reaction quotient in describing how equilibrium is re-established, the PowerPoint provides examples in how to account for such changes.
This is tailored for the Edexcel specification Topic 11.

Specification : Topic 11
1. be able to deduce an expression for Kp, for homogeneous and heterogeneous
systems, in terms of equilibrium partial pressures in atm
2. be able to calculate a value, with units where appropriate, for the equilibrium
constant (Kc and Kp) for homogeneous and heterogeneous reactions, from
experimental data
3. know the effect of changing temperature on the equilibrium constant (Kc and Kp),
for both exothermic and endothermic reactions
4. understand that the effect of temperature on the position of equilibrium is
explained using a change in the value of the equilibrium constant
5. understand that the value of the equilibrium constant is not affected by changes
in concentration or pressure or by the addition of a catalyst
