Consider two gases, A and B, are in a container at room temperature. What effect will the following changes have on the rate of the reaction between these gases? The temperature is decreased at a constant volume.

The effect that the following changes have on the rate of the reaction between the gases A and B in a container when the temperature is decreased at a constant volume will decrease because the molecules of A and B are ineracting very slowly due to the decrease in temperature which results to the decrease in kinetic energy.
