Question 1.
What is chemical equilibrium?
Show hintHide hint
Remember how reactions balance out.
Question 2.
What does Kp measure?
Show hintHide hint
Think about the relationship between products and reactants.
3Question 3.
What happens to concentrations of reactants and products at equilibrium?
- True
- False
Show hintHide hint
Think about balance in reactions.
4Question 4.
The Gibbs free energy is minimized at equilibrium.
- True
- False
Show hintHide hint
Focus on thermodynamic principles.
Question 5.
A reaction reaches equilibrium with Kp = 2.0 for the conversion of A(g) + B(g) ↔ C(g). If the partial pressures of A and B are both 0.5 atm at equilibrium, what are the partial pressures of C?
Show hintHide hint
Set up the Kp expression correctly, then rearrange to find the missing pressure.
Question 6.
Given ΔG⁰ = -15 kJ/mol for the reaction at 298 K, calculate the Kp for this reaction.
Show hintHide hint
Make sure to convert ΔG⁰ to Joules when using R in the calculations.
