Temperature's Effect on the Rate of a Chemical Change

Influence of temperature on the rate of chemical change Introduction This study is about how the temperature affects the chemical change rate of calcium carbonate formed by the reaction between solid marble chips and dilute hydrochloric acid. During the investigation, I will try to investigate how it influences the rate of chemical change of calcium carbonate and hydrochloric acid by changing solvent temperature. Since it is known to release carbon dioxide according to the following formula, for each experiment I performed, we measure the amount of carbon dioxide released from the reaction.

The change in temperature is a feature of chemical change. During the experiment, you can check the temperature change by immersing the thermometer in a beaker or Erlenmeyer flask. If the temperature rises like most reactions, chemical changes may occur. This is different from physical temperature change. Substances such as water are heated during physical temperature changes. In this case, however, one compound is mixed with another compound which produces the product. When the reactants are mixed, the temperature change induced by the reaction is an indicator of chemical change.

Note: A chemical reaction may occur when two or more reactants are mixed, and temperature and color change etc. are observed. These are not clear indicators; chemical reactions may not occur. Changes in color do not always change chemically. If you want to change the color of a substance at a scene other than a chemical reaction, such as car painting, that change is physical rather than chemical. This is because the composition of the car has not changed. be careful. Changes in the color of a substance are not necessarily indicators of chemical change. For example, changing the color of a metal does not change its physical properties. However, in chemical reactions, color change is usually an indication of the occurrence of reaction. Painted metal car does not change composition of metal material
