There are quite a few errors in this video that are common mistakes students encounter...i.e. using wrong numbers in calculations vs the number in the question, incorrect Kc units (mol dm-6!?!) and the final worked calculation example does not work as you have used the initial reactant concentration (questions states that these concentrations were allowed to go to equilibrium) as the equilibrium concentrations for the reactants.
