Chapter 6.6, Problem 6.10P

Label each statement about the following exothermic reaction as True or False.
   ${\text{4 NH}}_{\text{3}}(g){\text{ + 3 O}}_{\text{2}}\text{(g) }\stackrel{}{\rightleftarrows }2{\text{ N}}_{\text{2}}{\text{(g) + 6 H}}_{\text{2}}\text{O(g)}$
a. Increasing the temperature drives the equilibrium to the right.
b. Doubling the concentration of ${\text{N}}_{\text{2}}$ drives the reaction to the left.
c. Increasing the pressure by adding an inert gas like helium has no effect on the direction of equilibrium.
d. Removing ${\text{H}}_{\text{2}}\text{O}$ drives the reaction to the right.
