Consider the following reaction at equilibrium: Predict whether the reaction will shift left, shift right, or remain unchanged after each disturbance. Drag the appropriate items to their respective bins. O2 is added to the reaction mixture KCIO3 is added to the reaction mixture KCl is added to the reaction mixture O2 is removed from the reaction mixture Shifts left Shifts right Remains unchanged Consider the following reaction: HC2H3O2(aq) + H2O(l) =H30+(aq) + C2H307- (aq) where...

The general form of a chemical reaction is aA + bB = cC +dD Where A and B are reactants in the forward direction and C and D are products in the forward direction. The lower case letters are the stoichiometric coefficients for the balanced equation. The general form of the equilibrium constant equation is then: Keq = [C]c[D]d/[A]a[B]b Part I: Q vs. K Q: reaction quotient can be calculated for a reaction at any concentration values of reactants and...
