Two chemicals, X and Y, react in solution to produce product Z. The initial rate of formation of product Z was measured in five experiments, 1-5, using different concentrations of X and Y. The results are shown in the table. Which statement is correct?
- AThe rate of the reaction is directly proportional to the concentration of reagent X.
- BThe rate of the reaction is directly proportional to the concentration of reagent Y.
- CThe rate of the reaction is not affected by the concentration of reagent X.
- DThe rate of the reaction is not affected by the concentration of reagent Y.
