How do you By measuring the quantity of a
measure the rate reactant used or the quantity of
of a reaction? product formed over time
,What is the Mean rate of reaction = quantity of
equation for reactant used/time taken
calculating the
mean rate of a
reaction by
measuring the
amount of
reactant used?
What is the Mean rate of reaction = quantity of
equation for product formed/time taken
calculating the
mean rate of a
reaction by
measuring the
amount of
product formed?
What units can g/s or cm3/s or mol/s
you measure the
rate of a reaction
in?
, How do you By measuring the gradient of a
calculate the rate tangent drawn at that specific time on
of a reaction at a the graph
specific time from
graph of the
quantity of
reactant used or
the quantity of
product formed?
What are the five Concentration of reactants in solution,
factors that can pressure of reacting gases, surface
affect the rate of area of solid reactants, temperature
a reaction? and the presence of a catalyst
What theory can Collision theory
we use to explain
how various
factors affect the
rate of a
reaction?
Chemical reactions can occur only
What is collision
when reacting particles collide with
theory?
each other and with sufficient energy
What is the The minimum amount of energy that
activation energy particles must have to react
of a reaction?
