VITETE EETLE 1. An experiment was carried out to determine the effects of two different variables on reaction
rate when solid calcium carbonate is combined with liquid dihydrogen monoxide. The reaction
was carried out multiple times and each trial used the exact same proportions of both
chemicals. The tables below show the data collected during the experiment. The dependent
variable measured was time for the reaction to finish.
