Calculate AH for the following reaction:
-
-
2NO2(g) → N204(9)
Use appropriate data from the following listing:
NO(g) + NO2(g) + O2(g) → N2O5(9) ΔΗ, = -113.7
NO(g) + NO2(g) → N2O3(g)
9
AH2 = -36.1
N205(9) ► N,05(s)
,
AH = -55.3
N2O3(g) + N2O3(s) -→ 2N204(9)
ΔΗ, = -8.100
2NO(g) + O2(g) → 2NO2(g)
ΔΗς = -112

Examine the false statement. When pressure is added to a reaction at chemical equilibrium, the reaction responds by increasing the amount of pressure it exerts on its surroundings. Select the rewording that makes the statement true.

A. When pressure is added to a reaction at chemical equilibrium, the reaction responds by increasing the rate of reaction, which will decrease the number of particles and offset the pressure.

B. When pressure is removed from a reaction at chemical equilibrium, the reaction responds by decreasing the amount of pressure it exerts on its surroundings.

C. When pressure is removed from a reaction at chemical equilibrium, the reaction responds by increasing the rate of reaction, which will decrease the number of particles and increase the pressure.

D. When pressure is removed from a reaction at chemical equilibrium, the reaction responds by decreasing the amount of pressure it releases to its surroundings.


E. When pressure is added to a reaction at chemical equilibrium, the reaction responds by decreasing the amount of pressure it absorbs from its surroundings.
