Chapter 15 QUIZ C
Name _________________________
4pts 1. Answer the following:
(a) What can you say about the relative concentrations
of reactants and products when the value of Kc is very
large?
(b) What is the unit on Kc for the following reaction:
2NH3(g) D 3H2(g) + N2(g)
4pts 2. Determine Kc for: 2HI(g) D H2(g) + I2(g) if the
initial concentration of HI is 0.800 and its equilibrium
concentration is 0.0884. Use an icebox.
2pts 3. The exothermic reaction: C(s) + CO2(g) D + 2CO(g) is
allowed to come to equilibrium. State the effect (shift
to the right, shift to the left, or no effect) if the
following conditions are changed:
a) CO2 is added __________________
b) the temperature is decreased __________________
c) C(s) is added __________________
d) pressure is increased by
addition of an inert gas __________________
