Chapter EQ, Problem 2PQ

Interpretation Introduction

Interpretation:

The option which is the correct $K_c$ expression for the reaction given below has to be chosen.

  $P_4\left(s\right)+6C{l}_2\left(g\right)\rightleftharpoons 4PC{l}_3\left(g\right)$

Concept Introduction:

Consider a general equilibrium reaction.

  $aA+bB\rightleftharpoons cC+dD$

The expression of $K_c$ for the above reaction can be written as given below.

  $K_c=\frac{{\left[C\right]}^c{\left[D\right]}^d}{{\left[A\right]}^a{\left[B\right]}^b}$
