Problem

Consider the following reaction: 2S(s) + 3O 2(g) → 2SO3(g) + heat

The rate of this reaction could be increased by

A. Decreasing temperature

B. Adding a catalyst

C. Increasing the concentration of S(s)

D. Increasing the concentration of SO 3(g)

Solution

We’re asked to determine which conditions would increase the rate of this reaction between sulfur and oxygen gas.

Additionally, remember the Le Chatelier’s principle: If a system (chemical reaction) is at equilibrium and we disturb it then the system will readjust to maintain it’s equilibrium state.
