For an exothermic reaction, a temperature increase causes the value of K to do what?
|
For an exothermic reaction, a temperature increase causes the value of K to decrease. Then, because Q>K, the reaction shifts toward reactants.
The opposite occurs for endothermic reactions. |
|
When the stoichiometry of a reaction changes how does the new equilibrium constant change?
|
When the stoichiometry of a reaction changes, the new equilibrium constant is raised to the same power. Thus, if a reaction is multiplied by 2, the equilibrium constant K is squared.
|
|
If Q < K
which way does the reaction go? |
to the Right ---->
to form more Products |
|
If Q > K
which way does the reaction go? |
to the Left <----
to form more Reactants |

When a given balanced equation has a value of Kc = n
What is the Kc for the reverse of that equation? |
1/n
|
|
When a given balanced equation has a value of Kc = n
What is the new Kc if you multiply the equation by 2? |
n^2
