Mary J. Bojan Chem 110 Le Chatelier’s Principle To illustrate this principle use the following chemical system in a closed 1L container: Δ H rxn = 466kJ/mol T = 500K Initial conditions: [HBr] = 4.0M [O 2 ] = 1.0M [H 2 O] = 0.0M [Br 2 ] = 0.0M At equilibrium: [HBr] = 1.0M [O 2 ] = 0.25M [H 2 O] = 1.5M [Br 2 ] = 1.5M What is K c ? 4HBr(g) + O 2 (g) 2H 2 O(g) + 2Br 2 (g)
