Cl2(g)+H2O(g)2HCl(g)+1/2O2(g) (a) Calculate the rH and rU per mole of HCl produced. (b) If 100 grams of Cl2 (g) and 150 grams of H2O(g) was present initially and only 10kJ of heat was added to the reaction at constant pressure and at 500C, calculate the composition of the product (%mol) and the fractional conversion of the limiting reactant.
