What is the equilibrium constant of the reverse reaction for the following reaction? PCl5(g) ⇌ PCl3(g) + Cl2(g)

Knowing that: [PCl5] = 0.00325 M, [PCl3] = 2.52 M and [Cl2] = 0.02175 M at equilibrium.

Ais your answer to this

Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place.

The question is incomplete. complete question is attached belowanswer: correct answer is option b  i.e.  solid particles  reason: filter paper has small pores, through which smaller particles can pass through. however, solid particles  have relatively larger size. hence, they are least likely to pass through.
