__________ explains the equilibrium constant for any chemical reaction.

A. Henry's law

B. Law of mass action

C. Hess's law

D. None of these

Answer: Option B

Solution(By Examveda Team)

Law of mass action in mathematical form can be expressed as :
For an equilibrium reaction \[aA=bB\leftrightarrow cC=dD\]
$${K_c} = \frac{{{C^c}{D^d}}}{{{A^a}{B^b}}}$$
Hence we can say it explains about equilibrium constant.
