Question

What is keq for the reaction 2so2(g) + o2(g) 2so3(g)? apex?

Answer 1

The  keg for the reaction
2  SO2(g) + O2(g)   →  2  SO3(g)  is

 Keg =  [SO3]^2/ {(SO2)^2 ( O2)}

Keg (equilibrium constant)  is the ratio of  of equilibrium  concentration  of the product   raised  to the power  of their  stoichiometric  coefficient  to the  equilibrium  concentration  of the reactant  raised  to the power  of  their stoichiometric  coefficient.

Answer 2

Answer: The $K_{eq}$ for the reaction is $K_{eq}=\frac{[SO_3]^2}{[SO_2]^2[O_2]}$

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients. It is represented by $K_{eq}$

For a general chemical reaction:

$aA+bB\rightarrow cC+dD$

The $K_{eq}$ is written as:

$K_{eq}=\frac{[C]^c[D]^d}{[A]^a[B]^b}$

For the given chemical reaction:

$2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)$

The $K_{eq}$ is represented as:

$K_{eq}=\frac{[SO_3]^2}{[SO_2]^2[O_2]}$

Hence, the equilibrium constant for the reaction is given above.
