Question

Consider the reaction of SO2​ and O2​ described by the chemical reaction below. Determine the equilibrium constant for this reaction by constructing an ICE table, writing the equilibrium constant expression, and solving it. Complete Parts 1-2 before submitting your answer. 2SO2​( g)+O2​( g)⇌2SO3​( g) A 2.00 L reaction vessel was filled 0.0432 molSO2​ and 0.0296 molO2​ at 900 K and allowed to react. At equilibrium, the concentration of SO3​ was found to be 0.01752M. Fill in the ICE table with the appropriate value for each involved species to determine concentrations of all reactants and products. Incorrect, 1 attempt remaining

Answer 1

The ICE table for the reaction is shown in the answer below for each specie.

Number of moles of
`SO_2` = 0.0432 mol/2 L

= 0.0216 M

Number of moles of oxygen = 0.0296 mol/2 L

= 0.0148 M

Equilibrium concentration of
`SO_3` = 0.01752 M

The ICE table will look like this;

2
`SO_2`(g) +
`O_2`(g) = 2
`SO_3`(g)

I 0.0216 0.0148 -

C -2x -x +2x

E 0.0216 - 2x 0.0148 - x 0.01752
