Answer: Thus the value of the equilibrium constant is [tex]2.4\times 10^1[/tex]
Explanation:
Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.
[tex]PCl_3(g)+Cl_2(g)\rightleftharpoons PCl_5(g)[/tex]
At eqm. conc. (0.20) M (0.25) M (1.20) M
The expression for equilibrium constant for this reaction will be,
[tex]K_c=\frac{[PCl_5]}{[PCl_3][Cl_2]}[/tex]
[tex]K_c=\frac{1.20}{0.20\times 0.25}=24=2.4\times 10^1[/tex]
The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
Thus the value of the equilibrium constant is [tex]2.4\times 10^1[/tex]
