During a reaction involving gases, the pressure is increased. Would this increase or decrease the speed of the reaction. Why? A. Increase because the pressure will cause an increase in kinetic energy and result in faster moving particles. B. Decrease because an increase in pressure means increase in volume which will spread the particles farther apart. C. Increase because the particles are closer together and more likely to collide. D. Decrease because the particles are closer together and cannot move as fast so the collisions are less successful.
