1010 - Reaction Quotient |
1010 - Define reaction quotient (Q). |
1020 - Recognize Q changes as a reaction progresses but K does not (at a given temperature). |
1030 - Use Q to determine the direction in which a reaction will progress, given K. |
1040 - Use Q to measure reaction progress towards equilibrium. |
1020 - Equilibrium Concentrations |
1010 - Undestand an ICE table reveals how a reaction changes from initial to equilbrium concentrations. |
1020 - Use ICE tables to relate equilibrium concentration to initial conditions using a single variable (x). |
1030 - Determine equilibrium concentrations given a K value and one or more equilibrium concentrations. |
1040 - Use ICE tables to relate the equilibrium concentrations, initial concentrations and K. |
1050 - Apply the x is small aproximation to simplify a solution. |
1060 - Know the x is small approximation is valid if x is less than 5% of the concentration compared. |
1030 - Disturbing Equilibrium |
1010 - Recognize that disturbing a reaction at equilibrium changes Q to a value other than K. |
1020 - State Le Chateliers principle, that a system disturbed from equilibrium will return to equilibrium (Q will return to K). |
1030 - Predict how equilibrium shifts as concentration, presssure or volume of a reaction are disturbed. |
1040 - Predict how K changes with temperature (T) for an exothermic or endothermic reaction. |
