How does increasing the pressure of reacting gases affect the rate of reaction? Explain your answer.

Increasingthe pressure of reactinggases usually increases the reaction rate. This is because higher pressure compresses the gas molecules, resultingin more frequent collisions between them, which increases the likelihood of successful reactions.

This question tests the student's understandingof the relationship between gas pressure and reaction rate, specifically how pressure influences collision frequency. A stronganswer demonstrates knowledge of collision theory and its application to gas reactions.
