When H₂(g) reacts with Cl₂(g) to form HCl(g) according to

When H₂(g) reacts with Cl₂(g) to form HCl(g) according to the following equation, 44.2 kcal of energy are evolved for each mole of H₂(g) that reacts. H₂(g) + Cl₂(g) →2HCl(g) Is this reaction endothermic or exothermic? How many kcal of energy are evolved if 1.40 mol of H₂(g) reacts?
