a lab group wanted to determine if changing the concentration of the reactants would affect the reaction rate during the first 10 seconds of the reaction. they conducted four experiments, each with different starting concentrations. after a series of trials, the students produced the following data table: experiment initial x initial y rate of production of z (m/s) experiment 1 0.20 m 0.20 m 0.015 experiment 2 0.40 m 0.20 m 0.060 experiment 3 0.20 m 0.40 m 0.030 experiment 4 0.40 m 0.40 m 0.120 which of the following conclusions is supported by the data? choose 1 answer: a the reaction rate is increased only by increasing the concentration of x. b the reaction rate is increased only by increasing the concentration of y. c the reaction rate is increased by increasing the concentrations of either x or y. d increasing the concentration of the reactants has no effect on the rate.

Answer

Brief Explanations:

Compare the experiments. When comparing Experiment 1 and 2, [X] increases while [Y] is constant and the rate increases. When comparing Experiment 1 and 3, [Y] increases while [X] is constant and the rate increases. This shows that increasing the concentration of either X or Y increases the reaction - rate.

Answer:

C. The reaction rate is increased by increasing the concentrations of either X or Y.
