The reaction of bromoethane with sodium acetate affords the substiution product methyl acetate what is the effect of doubling the concentration of sodium acetate on the rate of the reaction?
A. the rate remains the same.
B. the rate decreases by a factor of 2.
C. the rate increase! by a factor of 2.
D. the rate increases by a factor of 4.

The correct answer is option C. "the rate increase! by a factor of 2".

Explanation:

The rate of a typical chemistry reaction is positively affected by the concentration of the substrate. Where the more concentrated the substrates are, the faster the reaction occurs. In this case, doubling the concentration of sodium acetate will double the rate of the reaction, since sodium acetate have a positive effect in the reaction by acting as a substrate along with bromoethane.
