Which way will the following equilibrium shift if you increase the container size? What if you decrease? 2NoCl = 2NO + Cl(2) | Increase = right shift, decrease = left shift |
Which way will the following equilibrium shift if you increase the container size? What if you decrease? H(2)+ I(2) = 2HI | No shift |
Does a negative delta H mean temperature is a reactant or product? | Delta H = (Products) - (Reactants), so a negative (delta H) means it is a product |
If delta H < 0, the reaction is said to be... | Exothermic (gives off heat) |
If delta H > 0, the reaction is said to be... | Endothermic (requires heat) |
Given the initial concentrations of a reaction, and then the concentrations at equilibrium, how do you find Kc? | ICE chart to find any missing information; then use the equation Kc=(products)/(reactants) |
What happens when Qc > Kc? | Qc will decrease until it equals Kc |
If Qc is decreasing, what do the reactants do? | Increase- (a forward reaction uses up A & B to make C, but the reverse reaction is using up C to make A & B) |
Kp only equals Kc when.. | The number of moles of gas are equal on both sides |
When you increase the pressure, which way will the equilibrium shift? | To the side with the least number of gas molecules |
If Q > K | reaction moves towards reactants |
If Q < K | reaction moves towards products |
