Express your answer to one significant figure and include the appropriate units Figure 1o Transition states 300 200 100 EValue Units 0. Submit My Answers Give Up A -100 1 Products Reactants -200 Part C What is the reverse-direction activation energy for reaction A? Express your answer to one significant figure and include the appropriate units. Start - Finish Reaction coordinateExplanation / Answer
a)
forward direction Ea --> Etop - Ereactatn
Etop(A) = 200 approx
Ereactants(A) = -200
Ea = 200--200= 400 kJ
B)
fowrad direction Ea for B:
Etop B = 300
Ereactants B = -100
Ea forward B = 300 --100 = 400 kJ/mol
C)
reverse reaciton for A:
EA reverse A= Etop - Eproducts = 200- 0= 200 kJ
D)
reverse for B
Ea reverse B = Etop -Eproducts = 300 --200= 500 kJ
