Variables affecting the rate of homogeneous reactions are___________________?
Correct answer: D. Pressure, temperature and composition
- A. Pressure and temperature only
- B. Temperature and composition only
- C. Pressure and composition only
- D. Pressure, temperature and composition
Explanation
Homogeneous reaction rates can change with composition through concentration, with temperature through the rate constant, and with pressure, especially for gas-phase systems. Thus pressure, temperature and composition are all relevant variables.
