For a given reaction, the rate law is Rate = k[A][B]. What happens to the rate if the concentration of A is doubled and B is halved?

A. The rate remains the same
B. The rate is doubled
C. The rate is halved
D. The rate is reduced by one-fourth

Answer: The rate remains the same


Additional Information: Doubling A doubles the rate, but halving B reduces the rate by half, resulting in no overall change.
