How much heat, in calories, is needed to raise the temperature of 125.0 g of Lead (Clead= 0.130
J/gºC) from 17.5°C to 41.1°C?

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?
