Kinetics and Equilibria

?
Define rates of reaction?
The change in conc/mass/volume in a unit of time.
1 of 6
Why does a reaction decrease as time increases?
There are less particles to collide so less collisions. Particles are also further apart.
2 of 6
Define activation energy?
The minimum energy required for a successful collision to start a reaction.
3 of 6
During decomposition a substance?
Is used up
4 of 6
What must happen before molecules can react?
They must have the min activation energy and collide.
5 of 6
Why does decomposition occur at a higher temperature?
More energy, more molecules have the minimum Ea.
