Question 27 1 pts Which idea listed below is not a part of the collision theory of reaction rates? All molecular collisions result in a reaction. Only effective collisions result in a chemical reaction. Molecules must collide to react. Molecules must be properly oriented when they collide to react. Molecules must collide with enough kinetic energy to overcome the potential energy stabilization of the bonds.

Question 28 1 pts The questions below refer to the following diagram: Potential bergy All Reaction progres. If the reaction were reversible, would the forward or the reverse reaction have a higher activation energy? The forward activation energy would be greater. The forward and reverse activation energies are equal. none of these The diagram shows no indication of any activation energy. The reverse activation energy would be greater.

Question 29 1 pts Equilibrium is reached in chemical reactions when none of these the rates of the forward and reverse reactions become equal the concentrations of reactants and products become equal the temperature shows a sharp rise all chemical reactions stop D Question 30 1 pts Which of the following statements about the reaction quotient, Q. is false? If Q<Kc, the reaction must move to equilibrium by forming more products. O none of these Of Q> Kc the reaction must move to equilibrium by forming more reactants. Its value is calculated using nonequilibrium concentrations It has the same expression as Ke. SC Š & 7 5 0) 00 8 E R T Y

Question 31 1 pts Consider the following equilibrium: 2NOCI(g) 2NO(g) + Cl2(g) with K - 1.6 x 10-5. In an experiment, 1.00 mole of pure NOCI and 1.00 mole of pure Cl2 are placed in a 1.00-L container. What is the equilibrium concentration of NO? (no algebra necessary....just set up your ice table) none of these -X O -2x 0 x² OX

D Question 32 1 pts For the following system at equilibrium, H2(g) + CO2(g) → H2O(g) + CO(g) the addition of H2(g) would cause (according to LeChatelier's principle) more H2O(g) and CO(g) to form. only more H2O(g) to form. none of these O only more CO2(g) to form. O only more CO(g) to form.
