When hydrogen reacts with iodine, we can show the reaction as follows
h-h + 1-1>
2(h-1)
(a)
given the following bond energies, calculate the heat of reaction
(h - h: 436, 1-1: 151kj, h-1: 298kj)

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
