Rate of reaction. How does varying the concentration of Hydrochloric acid in reaction with Marble chips affect the rate of Carbon Dioxide being given off? Hypothesis: Chemical kinetics, the study of reaction rates, shows that three conditions must be met at the molecular level if the reaction is to occur: * the molecules must collide * they must be positioned so that the reacting groups are together in a transition state between reactants and products * the collisions must have enough energy to form a transition state and form into products Some reactions need energy to react, others are spontaneous once all reactants are mixed. When a solution of substances doesn't need any energy to react it is said to be unstable, that is due to the substances having enough energy in their molecular collisions to form a transition state (the state in which both chemicals have broken apart either from their old pairs or from...
