Use the reactions provided below and their associated enthalpies to find delta_rH for the reaction PCl_3(l) + Cl_2(g) rightarrow PCl_5(s) at 25 degree C and 1 bar, (b) Calculate the corresponding enthalpy of reaction a 65 degree C if delta_r C_p, m = -50 J K^-1 mol^-1 (constant from 25-65 degree C). Does the reaction enthalpy increase or decrease with temperature? Given reactions (25 degree C, 1 bar): 2 P(s) + 3 Cl_2(g) rightarrow PCl_3(l) delta_rH = -640 kJ/mol Reaction 1 2P(s) + 5 Cl_2(g) rightarrow 2 PCl_5(s) delta_rH = -886 kJ/mol Reaction 2
