Answer
When the pressure is increased, the particles are forced closer together. This results in a higher frequency of collisions between reactant particles, leading to a higher likelihood of successful reactions.

Answer
Shape B is more effective because it has a greater surface area. A larger surface area allows for more frequent collisions between the catalyst and reactant particles, speeding up the reaction.
