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 concentration of the reactants change the reaction rate?

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

Answer 1

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

Step-by-step explanation:

In the given question the data with change in different factors affect the rate of reaction differently as it alters the time it takes to complete reaction:

Conditions Reaction Time

Original 10 seconds

Higher concentration 5 seconds

Higher temperature 5 seconds

Metal added 5 seconds

As it is given above, time is decreased in each condition including in the case of increasing the concentration of the reactants which means the rate of reaction increases as well.
