Question 3 of 10

3. Question
1 point(s)
Why does increasing gas pressure cause the reaction rate to increase?
- The number of gas molecules in the container increases.
- The kinetic energy of the gas molecules increases significantly.
- The number of reactant molecules per unit volume increases.
- The size of gas molecules becomes smaller so that they collide more easily.
Correct
