Rate of any reaction depends upon:
Correct answer: E. All of the above
- A. Temperature
- B. Concentration
- C. Pressure
- D. Rate constant
- E. All of the above
Explanation
The rate of reaction depends on the concentration of reactants, temperature, pressure (in case of gaseous reactants), and catalyst. All of these factors are interconnected and influence the rate of a reaction. Therefore, the correct answer is that the rate of any reaction depends on all of the above factors (temperature, concentration, pressure, and rate constant).

About Factors Affecting Rate of Reaction
Reaction rate depends on the nature and concentration of reactants, pressure for gases, temperature, surface area and catalysts. Collision theory explains these effects through collision frequency, orientation and activation energy, while questions often distinguish a catalyst's effect on reaction rate from its lack of effect on equilibrium composition.
