Two gases combine to form one product. Raising the pressure changes the rate of this reaction. Platinum is used as a catalyst. Which row states one effect of increasing the pressure on this reaction and one effect of adding platinum to this reaction?
- AThe rate of the reaction decreases. The activation energy, $E_a$, decreases.
- BThe rate of the reaction decreases. The activation energy, $E_a$, increases.
- CThe rate of the reaction increases. The activation energy, $E_a$, decreases.
- DThe rate of the reaction increases. The activation energy, $E_a$, increases.
