Asample of water is taken and kept in a beaker in a freezer at a constant temperature of 0°c. if the system is at dynamic equilibrium, which of these statements is true? a. the rate of freezing is equal to the rate of melting. b. the rate of freezing is greater than the rate of melting. c. the amount of ice is greater than the amount of water. d. the amount of ice is equal to the amount of water.

A system is said to be at dynamic equilibrium if the rate of forward reaction is equal to the rate of the backward reaction.

In the given example, the equilibrium can be represented as:-

Liquid water ↔ Solid Ice

The forward reaction involves conversion of water from liquid to solid (freezing) whereas the reverse involves the conversion of ice to liquid water(melting).

Hence, at dynamic equilibrium the rate of freezing is equal to the rate of melting.

Ans A)

A. The rate of freezing is equal to the rate of melting.

Explanation:

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
