Total questions: 13
Worksheet time: 18mins
According to collision theory, how does an increase in temperature affect the rate of reaction?
It decreases the rate of reaction.
It has no effect on the rate of reaction.
It increases the rate of reaction.
It stops the reaction completely.
What is the primary reason that increasing temperature increases the rate of reaction according to collision theory?
It increases the concentration of reactants.
It increases the energy of collisions between particles.
It decreases the activation energy required.
It changes the state of reactants.
Which of the following best describes activation energy?
The energy required to start a reaction.
The energy released during a reaction.
The energy absorbed by the products.
The energy lost to the surroundings.
In a practical experiment, if the temperature of a reaction mixture is increased from 20°C to 30°C, what is the expected effect on the rate of reaction?
The rate of reaction will decrease.
The rate of reaction will remain the same.
The rate of reaction will increase.
The reaction will stop.
What is the effect of temperature on the frequency of collisions between reacting particles?
Temperature decreases the frequency of collisions.
Temperature has no effect on the frequency of collisions.
Temperature increases the frequency of collisions.
Temperature causes collisions to become less effective.
When the temperature of a reaction increases, the rate of reaction (a) .
Order these into how increasing temperature affects the rate of reaction
Particles gain kinetic energy
Particles move faster
Particles collide more frequently
The rate of reaction increases
Which graph shows the reaction which was performed at a higher temperature?
Sort the following into "Factors that affect the rate of reaction" and "Not factors that affect the rate of reaction"
Temperature
Presence of a catalyst
Surface area
Colour of reactants
Volume of the container
Higher temperature increases the rate of reaction because particles have more (a) and collide more (b) .
Categorise the statements as “True” or “False”
Increasing temperature decreases the rate of reaction
Increasing temperature gives particles more energy
Lowering temperature makes collisions less frequent
Particles need to collide with enough energy to react
As temperature increases, the particles have more energy, and there are more (a) collisions
Sort the statements as “Effect of increasing temperature” or “Effect of decreasing temperature”
Particles move faster.
More frequent collisions.
Fewer particles with activation energy.
Rate of reaction decreases.
