Which of the following is not a unit of the equilibrium constant K_p? (where, Δx = number of moles of products number of moles of reactants)

A. (atm)^Δx, when Δx is negative

B. (atm)^Δx, when Δx is positive

C. Dimensionless, when Δx = 0

D. (atm)^Δx2, when Δx > 0

Answer: Option D

Solution(By Examveda Team)

The equilibrium constant $$\left( {{K_P}} \right)$$   for the reaction below can be written as : $${K_P} = {\left( {atm} \right)^{\Delta x}}$$
Where $$\Delta x = $$   change in number of moles (difference in number of moles of products $$-$$ reactants).
