Consider the following thermochemical equations. Reaction A,H° / kJ mol"
N0(g) + 1/2 C|2(g) —> NOC|(g) -37.7s
N0(g) + 1/2 02(9) —> N02(g) -56.53
2 N02(g) —> N204(g) —53.03 What is ArH" for the reaction below? N204(Q) + 02(9) —’ 2 NOCKQ) + 02(9) Give your answer in kJ mol“, accurate to two decimal places. Do not include units in your answer. Ari-P: Number k-JmOI'1

Top Answer

NO + 1/2 Cl2 .............> NOCl ..................> delta H = -37.78 KJ / mole.. multiply by 2, we get 2 NO + Cl2... View the full answer
