Chemical Equilibrium
Question | Answer |
---|---|
Which of the following statements are FALSE? | K>>1 implies that the reaction is very fast at producing products. |
Give the direction of the reaction, if K>>1. | The forward reaction is favored. |
Give the direction of the reaction, if K<<1. | The reverse reaction is favored |
Give the direction of the reaction, if K~1 | Neither direction is favored |
Dynamic equilibrium occurs | when the rate of the forward reaction equals the rate of the reverse reaction |
In a reaction mixture containing only reactants, what is the value of Q? | 0 |
In a reaction mixture containing only products, what is the value of Q? | infinity |
In a reaction mixture containing reactant and products, each at a concentration of 1M, what is the value of Q? | 1 |
If Q=K | it means the reaction is at equilibrium |
If Q>K | it means the reverse reaction will proceed to form more reactants |
If Q | it means the forward reaction wil proceed to form more products |
Identitfy the change that will always shift the eqilibrium to the right | decrease volume |
Reaction favors formation of more products | Q |
Reaction is at equilibrium | Q=K |
Reverse reaction is favored | K<<1 |
Reaction does not strongly favor reactant or products | K~1 |
Reaction will favor formation of reactants | Q>K |
Reaction has a larger amount of products than reactants | Q>>1 |
Define Le Chatelier's Principle | states that when a chemical system at equilibrium is disturbed, the system shirts in a direction that minimizes the disturbance |
