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