How is the instantaneous rate at time t obtained from a concentration–time graph?
Which change will increase the rate of a reaction by increasing the frequency of successful collisions?
What happens to the instantaneous rate as a reaction proceeds (for most reactions with no other changes)?
How does increasing the temperature generally affect the rate of a chemical reaction?
If 30 cm3 of gas is produced in 60 s, what are the correct units for the reaction rate calculated from this data?
Which of the following best describes how you obtain the initial rate from experimental volume–time gas data?
On a graph showing product amount vs time that flattens to a plateau, what does the plateau represent?
Which statement best describes the collision theory explanation for reaction rates?
If doubling the concentration of A causes the reaction rate to double, what is the order of reaction with respect to A?
An experiment gives concentration data: [A] falls from 0.40 mol dm-3 to 0.10 mol dm-3 in 30 s. What is the average rate of decrease of [A]?
Why is a line of best fit used for plotted experimental points when calculating rates?
