An experiment is performed to determine how concentration affects the rate of reaction. In each of four trials, equal volumes of solution A and solution B are mixed while temperature and pressure are held constant. The concentration of solution B is held constant, but the concentration of solution A is varied. The concentration of solution A and the time for the reaction to go to completion for each trial are recorded in the data table below.

73 On the grid in your answer booklet, mark an appropriate scale on the axis labeled “Reaction Time (s).” [1]

74 On the same grid, plot the data from the data table. Circle and connect the points. [1]
