Question
In the diagram above which label or labels correspond to intermediates, if any: both B & C B only alpha & beta A, B & C none of these if correct From the same diagram calculate the activation energy for the reaction, C rightarrow B 45 kJ/mole 4 kJ/mole 15 kJ/mole -45 kJ/mole 7 kJ/mole Which step in the reaction sequence is most likely an equilibrium step in which the components are in rapid equilibration? A B B C C D NONE of these steps are likely to be in equilibrium ALL of these steps are likely to be in equilibriumExplanation / Answer
19)
both B and C are intermediate
alpha, beta and gamma are acticated complex
Answer: A
20)
activation energy for C to B = E (B) - E(C)
=75 KJ/mol - 30 KJ/mol
= 45 KJ/mol
Answer: A
21)
Answer: C
Since actication energy of forward and backward reaction are almost equal
