Frequently asked questions

What factors increase the rate of reaction?

Higher temperature, concentration or pressure, larger surface area, and adding a catalyst.

What is dynamic equilibrium?

The forward and reverse reactions happen at the same rate in a closed system, so concentrations stay constant.
