# Need urgent help with this question watch

2. So you know X is a product.
So graph 1: as the temp increases, the conc of X decreases. When the temp increases it favours the endothermic reaction(meaning conc of x would increase if the reaction was endothermic) and therefore the forward reaction has to be exothermic (since the conc of X decreases as temp increases)
Graph 2: as pressure increases, X increases. You know that as pressure increases it favours the side with less moles and therefore there needs to be a decrease in number of moles of gas
Hope that helps! x

Can u help with theIs Question too plz

I would say C is wrong. This as an increase in pressure favours the side with the fewer moles. In this case its 1mol—>2 mols therefore favours lefthand side so should be more Cl2 molecules than Cl atoms xx
6. Is this GCSE Or A level
