CHEM 105bL Lecture Notes - Dinitrogen Tetroxide, Equilibrium Constant, Chemical Equation
Document Summary
Equilibrium position: moles of base added = moles of acid initially. When the forward reaction is equal to the reverse reaction. Equilibrium constant: ratio of products over reactants at equilibrium. Coefficients of the balanced chemical equation are the exponents. Q: used to determine which direction the reaction will continue in to reach equilibrium. K: the constant of a reaction at equilibrium (products/reactants) 3. for the following three reactions, decreasing the volume of the reaction flask has a different effect on the equilibrium position: 2 h2s + o2 (g) Double the pressure, half the volume, moves towards the direction where there are less moles of gas. **solids and pure liquids are not included in formula** Q>k, favors reactants, left: co (g) + h2o (g) K= 1 x 1 / 1 x 1. Assume that each reaction is at equilibrium with 1 atm of each gas present.
