Marble Chips Experiment Rates Of Reaction

These are reactions that transfer energy to the surroundings.

Marble chips experiment rates of reaction.

Caco3 2hcl h2o co2 this is the reaction we will be investigating. The rate of a chemical reaction can be measured either by how quickly reactants are used up or how quickly the products are formed. An investigation into how changing one variable influences the rate of reaction between marble chips and dilute hydrochloric acid planning section when dilute hydrochloric acid reacts with marble chips the following reactions occurs. In the investigation i am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small large pieces of marble chips calcium carbonate and hydrochloric acid per minute.

The rate of the reaction will decrease as hcl is consumed. Prediction when the concentration of acid increases more gas will be given off faster. Marble chips and hydrochloric acid rates of reaction planning aim to find if changing the concentration of an acid will increase or decrease the rate of the reaction when marble is dissolved in hydrochloric acid. As the size of the marble chips is increased then the reaction rate will decrease.

The rate of reaction can be calculated using the following equation. The rate of reaction increases this reaction between marble chips calcium carbonate and hydrochloric acid is an exothermic reaction. The energy is usually transferred as heat energy causing the reaction mixture and its surroundings to become hotter.
