Question

Decomposition of carbonic acid (h2co3) into water and carbon dioxide

Answer 1

Entropy is a measure of the degree of randomness of disorder of a system. The natural tendency of a system is for its entropy to increase. The formula for entropy is; $\Delta_s$ $=$ $q_{rev} \over T$

Entropy increases;

• With a change of state from solid to liquid, or liquid to gaseous state, or solid to vapour.
• When a substance is broken into multiple parts
• With increase in temperature
• When the total number of product molecules is greater than the total number of reactant molecules.

In this case,entropy;

1. Increases $\Delta_s \gt0$
