a) 4 and 24.) (8 pts) Consider the following reaction: 3 NO (e colorless H -156 kJ NO2( N2 red/orange colorless For each of the following changes predict what will happen to the equilibrium (shift right, left, or no effect) and what will happen to the concentration of NO (increase, decrease or stay the same form original equilibrium concentration) when the following conditions are changed. Direction of shift- NO] a) removing N2O b) increase volume: c) adding NO2. d) decrease temperature:

Explanation / Answer

3NO(g) <---------------> NO2(g)   +    N2O(g)      DH = -156KJ
colorless                red/orange      colorless
forward resction is exothermic reaction.Exothermic reaction takes place at
low temperature.
                             Direction of shift               [NO]

a. removing N2O                shift to right                 decreases
b. increase volume             shift to right                 decreases
c. adding NO2                      sift to left                   increases
d. decrease temperature      shift to right                decreases
