Question

8. Sulfur trioxide gas can decompose to produce sulfur dioxide gas and oxygen gas. This reaction sets up an equilibrium between the reactant and products. Write a balanced chemical equation for this situation. Report an equilibrium constant to 3 sig fig along with the temperature for this equilibrium citing a credible source (not Wikipedia, blogs, chegg.com, yahoo.com, etc.). Show any math work you need to do to convert the cited equilibrium constant to the equilibrium constant for your reaction. Do you expect mostly reactants, mostly products or about equal mixture of reactants and product? Explain your reasoning. a. b. c. 9. Fill in the missing values for the ICE chart for the reaction and calculate K for these conditions 2H,02(g) 2H20(g) O2(g) + I 0.100 M 0.050 M 0.025 M E 0.050 M 0.100 M

Explanation / Answer

Ans 9- given reaction with ICE TABLE

2 H2O2 = 2 H2O + O2

I 0.100 0.050 0.025

C - 2x +2x +x

E 0.100-2x 0.050+2x 0.025+x

Equilibrium concentration is given

0.050 = 0.100 - 2x

0.050 - 0.100 = - 2x

2x = 0.05

x = 0.025

The given table in complete format is

2 H2O2 = 2 H2O + O2

I 0.100 0.050 0.025

C - 0.050 +0.050 +0.025

E 0.050 0.100 0.050
