Science Chemistry C3 Effects On Reaction

Front 1

effect on increase temp. on rate of reaction?

Back 1

1) reactant particles move more quickly

2) they have more energy

3) particles collide more often, more collosions successful

4) rate of reaction increases

Front 2

graph of high temp.?

Back 2

steeper gradient at start

becomes horizontal sooner

Front 3

effect of concentration and pressue on rate of reaction/?

Back 3

changing concentrTION of reactant in solution or pressue of gaseoous reactant

1) reactant particles become more crowded

2) there is greater chance of particles colliding

3) rate of reaction increases

Front 4

what does the graph of higher concentration or pressue look like?

Back 4

steeper gradient at start

becomes horizontal sooner showing reaction is less

Front 5

effect of surface area of solid reactanton rate of reaction?

Back 5

1) more particles are exposed to other reactant

2) there are more collosions

3) rate of reaction increases

Front 6

how to increase surface area of reactant?

Back 6

cutting substance
