# Equilibrium watch

1. a) 2H2O2 (g) + O2 (g) --> 2H2O (g)

80% of 1.0 mol H2O2 (g) in a mixture with 1.0 mol O2 in a 1.0 dm3 flask reacts at a given temperature.

State the expression for Kcii.
Deduce the unitsiii.
Given the following data, evaluate the value of Kc

Study "help" means that we do not do homework. You should say what the problem is and show how far you have got with the question.
3. The confusion is the 80% and how to balance the equation
4. The 80% means that 80% of the one mole of H2O2 has reacted with one mole of oxygen to give H2O, so 0.8 moles of H2O2 has reacted.

Balance the equation by oxidation number method or by half equation method
