Chem II Test 3

QuestionAnswer
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
