Increasing the temperature of a chemical reaction has what effect?
Denatures the reactants
Decreases the rate of reaction
Increases the total collisions
Increasing the internal energy of the particles thereby increasing the number of collisions per second
How does a catalyst increase the rate of a reaction?
Lowers the activation energy
Lowers the deactivation energy
Raises the activation energy
Raises the deactivation energy
Which of these is a way to calculate the mean rate of a reaction?
Multiply the time taken by the amount of product formed
Divide the quantity of reactant used or product made by the time taken for the reaction to happen
HIGHER TEIR ONLY – How do we calculate the rate of a reaction from a reaction curve on a graph?
Make the curve a straight line and compare it to other graphs
Divide the top of the curve by the bottom
Draw a tangent to the curve and calculate the gradient of the tangent
What does the height of a rate graph tell you?
Rate of reaction
Rate of decrease
The amount of product formed
The surface area of the reactants
What does the gradient of a rate graph tell you?
Rate of reaction
Rate of decrease
The amount of product formed
The surface area of the reactants
