effect on increase temp. on rate of reaction? |
1) reactant particles move more quickly 2) they have more energy 3) particles collide more often, more collosions successful 4) rate of reaction increases |
|
graph of high temp.? |
steeper gradient at start becomes horizontal sooner |
|
effect of concentration and pressue on rate of reaction/? |
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 |
|
what does the graph of higher concentration or pressue look like? |
steeper gradient at start becomes horizontal sooner showing reaction is less |
|
effect of surface area of solid reactanton rate of reaction? |
1) more particles are exposed to other reactant 2) there are more collosions 3) rate of reaction increases |
|
how to increase surface area of reactant? |
cutting substance |
