A compressor raises the pressure of a mixture of two reacting gases. A cooler keeps the gases at a constant temperature.
What is the effect of this pressure increase on the average separation of the gas particles and the proportion of collisions that are successful?
The average separation stays the same and the proportion of successful collisions increases.
The average separation decreases and the proportion of successful collisions increases.
The average separation decreases and the proportion of successful collisions stays the same.
The average separation increases and the proportion of successful collisions stays the same.
