Question

A student repeats a reaction several times to test the effects of various

changes on the reaction rate. The data table shows the results. How does
increasing the temperature of the system change thereaction rate?

A. Increasing the temperature decreases the reaction rate.
B. Increasing the temperature increases the reaction rate.
C. More information is needed to determine what happens to the reaction rate.
D. Increasing the temperature has no effect on the reaction rate.

Answer 1

The correct answer is - C. Increasing the concentration increases the reaction rate.

Step-by-step explanation:

Answer 2

B. Increasing the temperature increases the reaction rate.

Step-by-step explanation:

The reaction time column displays how long the reaction ran for. If a reaction rate was fast then time taken for reaction to run would be slow right?

Therefore, original condition had reaction time of 10 second, but increaseing temperature lowered the time to 5 second, which must mean that reaction rate increased.
