| A | B |
|---|
| K>>1 | concentration of products is much greater than that of reactants at equilibrium. reaction strongly product-favored |
| K<<1 | concentration of products is much less than concnetration of reactants at equilibrium. is reactant favored |
| Q<K | reaction will move forward |
| Q=K | equilibrium |
| Q>K | reaction will move backward |
| k for a series of reactions is equal to... | the product of the K's of the individual steps |
| in general if you change the stoiochemtric coefficients by a factor of n the rule is | Knew=(Kold)^n |
| the k for the reverse reaction is... | the inverse of that of the forward reactin. Knew=1/Kold |
| Le Chateliers principle | if a system at equilibrium is distrubed, the ssytem tends to shift its equilibruim positino to counter the effect of the disturbance |
| Change T | change in K therefore change in P or concentrations at equilbrium |
| add or take away ractant or product | k does not change reactino adjusts to new equilbrium position |
| use catalyst | k not changed reaction comes more quickly to equilbrium |
| endothermic heat added | results in more products (forward reaction) |
| exothermic | heaat is product adding it will result in more reactants (reverse reaction) |
| increasing pressure will favor.. | favor the side of the equation that has fewer moles of gase |
| decreasing the pressure will.. | favor the side of the equation that has greater mole of gas |
| equilbrium and conentration | K is unchanged only equilbrium concentrations are changed |
