Question
Calculate the H for the reaction: CS2 + 2 O2 --> CO2 + 2 SO2. The heats of *
formation (in kJ/mol) for the substances are as follows: CS2 = 87.9; CO2 = -
393.5; SO2 = - 296.8
A. -1075.0 kJ
OB. +778.2 kJ
C. +288.0 kJ
O D. +87.9 kJ
Equilibrium is attained by the given reaction, N2(g) + 3H2(g) --> 2NH3(g)
Δ *
H = -. Predict the direction of the reaction that will be favored by the system
when the pressure is increased.
O A. Forward
B. Backward
C. No change
O D. Cannot be determined
