When nitrogen monoxide gas is mixed with oxygen gas, the molecules collide with each other.
Some of these collisions are effective and lead to a reaction.
The pressure of the mixture was increased at constant temperature.
Which row correctly describes how the frequency of effective and non-effective collisions changed?
| frequency of effective collisions | frequency of non-effective collisions | |
|---|---|---|
| A | increased | decreased |
| B | increased | increased |
| C | increased | unchanged |
| D | unchanged | decreased |
