Science 50

Two students performed an experiment to determine how concentration affects the rate of a chemical reaction. They performed four trials and recorded their data in Table 1.

In each of the 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 also held constant, but the concentration of solution A is varied.

Table 1

The students performed a second experiment, this time varying the concentration of solution B while keeping the concentration of solution A constant. Their results are presented in Table 2.
