What are three ways to increase the rate of dissociation of a solid

Three ways to increase the rate of dissociation of a solid are:

1. Increasing the surface area of the solute.

2. Increasing the temperature of the solvent.

3. Agitating the solute and solvent mixture.

Explanation:

The dissociation of a solid is defined as the separation of ions when an ionic compounds dissolve. The dissociation rate can be increased by increasing the surface area of the solute because it would get enough  chance to interact with other particles, hence the rate of dissociation increases.

By increasing the temperature, the kinetic energy of the molecules increase thereby dissolving more of the solute particles.

Agitating affects dissociation rate because it helps solute particle to get distributed evenly and hence gets dissociate easily.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
