Question

Calculate the standard reaction entropy for the decomposition of 1 mol calcite to carbon dioxide gas and solid calcium oxide at 25°c.

Answer 1

For the breakdown of 1 mol of calcite to carbon dioxide plus white precipitate oxide at 25°c, the standard reaction entropy is 160.6 J/mol*K.

How do you define reaction in chemistry?

In a chemical reaction, one or more materials known as reactants—are changed into one or more additional substances as products. Chemical elements or chemical compounds make up substances.

What kind of response?

Synthesis, decomposition, only one, double-replacement, and combustion are the five fundamental varieties of chemical reactions. You can classify a reaction into one of these groups by looking at the reactants and products. Several categories will apply to some reactions.
