61. What approximate effect does a 10K rise near room temperature have on rate?

Doubles
Halves
Increases by 10%
Quadruples

62. Which plot is used to find Ea experimentally?

Arrhenius plot
Van't Hoff plot
Eyring plot
Gibbs plot

63. Given high Ea, is the reaction fast or slow?

Slow
Fast
Instantaneous
Moderate

64. What diagram shows energy changes during a reaction?

Reaction profile
Phase diagram
Energy level diagram
Molecular orbital diagram

65. How is Ea of reverse reaction related to forward Ea and ΔH?

Ea(reverse) = Ea(forward) + ΔH
Ea(reverse) = Ea(forward) - ΔH
Ea(reverse) = Ea(forward)
Ea(reverse) = ΔH - Ea(forward)

66. What is the symbol for the specific rate constant?

Rate constant
Rate law
Reaction order
Equilibrium constant

67. What factors affect the rate constant?

Temperature
Activation energy
Catalyst
All of these

68. What are the units of k for a first-order reaction?

s^{-1}
L mol^{-1} s^{-1}
mol L^{-1} s^{-1}
s

69. Is the rate constant affected by concentration?

Independent of concentration
Depends on concentration
Depends on time
Depends on volume

70. How is k related to half-life for first-order?

k = 0.693/t_{1/2}
k = t_{1/2}/0.693
k = 0.693 t_{1/2}
k = 1/t_{1/2}
