Rate of reaction between hydrochloric acid and calcium carbonate calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas one way of following the rate of reaction at which it reacts is to measure the volume of carbon dioxide produced at certain time intervals during the reaction. A variable is something that can change match up the type of variable to the description control variable the variable that changes as a result of changing the independent variable this is the one you measure independent variable a variable that is kept constant (ie not changed) during an experiment dependent variable the one. Transcript of the effect of the concentration of hydrochloric acid on the bibliography results the data, somewhat, supports the hypothesis of the four graphs, three has the 20m solution at a higher rate than the 10m solution only two has the 20m solution higher than the 15m solutions, however question what is the effect of changing the concentration of hcl on the rate of reaction.
If the temperature is increased, the particles have more energy and so move quicker increasing the temperature increases the rate of reaction because the particles collide more often and with more energy look at the graph of the reaction between hydrochloric acid and calcium carbonate notice how. 01 introduction the rate of a chemical reaction depends on the frequency of the collisions between the atoms or ions of the reactants in this investigation the rate at which aluminum replaces hydrogen from a solution of hydrochloric acid.
