Question

what is your prediction for this experiment? a decreasing temperature will increase the reaction rate. b increasing temperature will increase the reaction rate. c temperature has no effect on the reaction rate. d increasing temperature will increase the reaction rate, up to a certain temperature. what is your strategy? a i will measure the height of the bubble column in tubes in which the same amount of enzyme is prepared at different temperatures. b i will measure the height of the bubble column in the same tube while varying the temperature.

Explanation:

For the prediction question, generally, increasing temperature increases the kinetic energy of reactant molecules and the frequency of effective collisions, thus increasing the reaction rate up to an optimal temperature after which the enzyme may denature. For the strategy question, measuring the height of the bubble column in the same tube while varying temperature allows for a controlled experiment to observe the effect of temperature on the reaction rate with a fixed - amount of enzyme.

Answer:

For "What is your prediction for this experiment?": D. Increasing temperature will increase the reaction rate, up to a certain temperature.
For "What is your strategy?": B. I will measure the height of the bubble column in the same tube while varying the temperature.
