Q
How does heat change the reaction time?
A
The heat makes particles move more rapidly and collide more frequently. When they collide, the bond between particles are broken and new bonds are easily formed. This causes the rate of reaction to increase.
1
Q
What is the rust word equation?
A
iron+water+oxygen—–>rust
2
Q
How does cooling change reaction time?
A
The lowered temperature slows does the chemical reactions.
3
Q
How does adding a catalyst change reaction speeds?
A
Catalysts speed up reaction speed
4
Q
Does adding more reactant speed up reaction?
A
Yes.
5
Q
How does increasing the surface area speed up reaction time?
A
It allows particles to mix more easily
6
Q
Does UV light speed up reactions?
A
Yes.
