Answer:
The correct answer is B.
The
is samller than
of the reaction . So,the reaction will shift towards the left i.e. towards the reactant side.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as ![K_{eq}](https://tex.z-dn.net/?f=K_%7Beq%7D)
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
![PCl_5(g)\rightleftharpoons PCl_3(g)+Cl_2(g)](https://tex.z-dn.net/?f=PCl_5%28g%29%5Crightleftharpoons%20PCl_3%28g%29%2BCl_2%28g%29)
The expression for
is written as:
![Q=\frac{[PCl_3][Cl_2]}{[[PCl_5]^1}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BPCl_3%5D%5BCl_2%5D%7D%7B%5B%5BPCl_5%5D%5E1%7D)
![Q=\frac{0.20 M\times 2.5 M}{0.20 M}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B0.20%20M%5Ctimes%202.5%20M%7D%7B0.20%20M%7D)
![Q=2.5](https://tex.z-dn.net/?f=Q%3D2.5)
Given :
= 0.0454
Thus as
, the reaction will shift towards the left i.e. towards the reactant side.
Hi there!
