Putting pressure on two gases that are reacting with each other will increase the reaction rate of the reaction between them. This is best explained by which of these.
A) Pressure acts as a catalyst and increases the reaction rate.
B) Pressure slows down the molecules making them more likely to react with each other.
C) This changes the orientation of the molecules making reactions more likely to occur.
D) Pressure reduces the volume that gases take up and this increases the frequency of the collision between them.
