The rate of a homogeneous reaction is a function of__________________?
Correct answer: D. All temperature, pressure and composition
- A. Temperature and pressure only
- B. Temperature and composition only
- C. Pressure and composition only
- D. All temperature, pressure and composition
Explanation
A homogeneous reaction rate can depend on composition through concentrations or activities, on temperature through the rate constant, and sometimes on pressure through gas-phase concentrations or fugacities. Therefore all three variables may affect the rate.
