C8 Rates and equilibrium Flashcards
1
Q
what ways can you find out the rate of reaction
A
monitor and measure the amount of reactants used up over time
measure the amount of product made over time
2
Q
what ways can you increase rate of reaction in a non reversible reaction
A
increase surface area of reactants
increase temperature
increase pressure
increase concentration
add a catalyst
3
Q
why does an increase in temperature increase rate of reaction
A
particles move more (more kinetic energy) so collide more
particles collide with more energy so more likely to have the energy required for reaction
4
Q
why does increasing concentration increase rate of reaction
A
increases the frequency of collisions
5
Q
why does increasing pressure increase rate of reaction
A
increases frequency of collisions
