Part a what is the numerical value of kc for the following reaction if the equilibrium mixture contains 0.51 m c3h6o, 0.30 m o2, 1.8 m co2, and 2.0 m h2o? c3h6o(g)+4o2(g)⇌3co2(g)+3h2o(g)
a) 2.4 × 101b) 1.1 × 104c) 8.9 × 10-5d) 4.3 × 10-2

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 .

The given balanced equilibrium reaction is,

 At eqm. conc.    (0.51) M   (0.30) M   (1.8) M    (2.0)M

The expression for equilibrium constant for this reaction will be,

Now put all the given values in this expression, we get :

Thus the value of the equilibrium constant is
