The Correct Option is D

Solution and Explanation

Concept: Reaction rate depends on concentration, temperature, and nature of reactants.

Step 1:
Temperature affects kinetic energy → affects rate.

Step 2:
Number of particles per mL = concentration → affects rate.

Step 3:
Bond stability affects activation energy → affects rate.

Step 4:
Pressure mainly affects gaseous systems, not liquids.
Conclusion:
Pressure does not influence liquid-phase reaction rate.
