N2(g) + O2(g) ↔ 2NO(g); ΔH = + 180.6 kJ mol-1
In the reaction above, increase in temperature will
increase the quantity of N2
increase in the yield of NO
decrease the yield of NO
decrease the quantity of O2
Correct answer is B

+3000 KJ mol-1
+300 KJ mol-1
-300 KJ mol-1
-3000 KJ mol-1
Correct answer is C
Heat, = -M C Q
= -50 * 4.2 * 14.3
= -300 KJ mol-1
M = Z/Q
M = Q/Z
M = Z/2Q
M = QZ
