How will change the rate of chemical reaction after 4 times pressure increase? (see q.1) A: not change C: increase in 4 times B: increase in 8 times D: increase in 16 times

The correct answer is C: increase in 4 times.According to the collision theory, the rate of a chemical reaction is directly proportional to the number of effective collisions between reactant molecules. When the pressure of a system is increased, the molecules are compressed into a smaller volume, leading to an increase in the frequency of collisions between them. This results in an increase in the rate of reaction.In this case, if the pressure is increased 4 times, the rate of reaction will also increase 4 times, assuming all other factors remain constant.
