Based on activation energies and energy changes and assuming that all collision factors are the same, answer the following questions:
(a) Which of the following reactions would be fastest in the forward direction?
Ea = 70 kJ/mol; E = 60 kJ/mol
Ea = 60 kJ/mol; E = 10 kJ/mol
Ea = 80 kJ/mol; E = -50 kJ/mol
Ea = 90 kJ/mol; E = -10 kJ/mol
(b) Which of the following reactions would be slowest in the forward direction?
Ea = 70 kJ/mol; E = 60 kJ/mol
Ea = 60 kJ/mol; E = 10 kJ/mol
Ea = 80 kJ/mol; E = -50 kJ/mol
Ea = 90 kJ/mol; E = -10 kJ/mol
(c) Which of the following reactions would be fastest in the reverse direction?
Ea = 70 kJ/mol; E = 60 kJ/mol
Ea = 60 kJ/mol; E = 10 kJ/mol
