Mixture of 1.80mol of hydrogen and 1.20 mol of gaseous chloride was sealed in a container. The mixture was left to reach equilibrium as..?
H2 + Cl2 (double arrow) 2HCl
At a given temperature the equilibrium mixture contained 2.15mol of hydrogen chloride.
(1) Calculate the amount in moles, of hydrogen and of chlorine in the equilibrium mixture by using an ice table.
I have in class notes, I can't see where the -1.075 and the 0.725 comes from?
