Step 1: Analyze the equilibrium reaction for Question 39. The given equilibrium reaction is: PCl_5(g) PCl_3(g) + Cl_2(g) H positive This indicates that the forward reaction (decomposition of PCl_5) is endothermic (absorbs heat). Also, the number of moles of gas increases from the reactant side (1 mole of PCl_5) to the product side (1 mole of PCl_3 + 1 mole of Cl_2, totaling 2 moles of gas). Step 2: Evaluate each statement for Question 39 based on Le Chat
