Answer:
Explanation:
If the rate of formation of B is set to be zero in the reaction scheme A → B → C, then the concentration of B can be determined using the rate equations for the forward and reverse reactions.
Let's assume the initial concentration of A is [A]. According to the reaction scheme, A converts into B, and then B converts into C.
The rate equation for the formation of B (A → B) is given by:
Rate₁ = k₁[A]
The rate equation for the conversion of B to C (B → C) is given by:
Rate₂ = k₂[B]
Since the rate of formation of B is set to be zero, the rate equation for the formation of B (Rate₁) becomes zero:
0 = k₁[A]
From this equation, we can determine that [A] = 0 or k₁ = 0.
If k₁ = 0, it means that the forward reaction (A → B) does not occur. In this case, B is not formed, and its concentration is zero.
Therefore, the concentration of B is given by:
[B] = 0
In summary, if the rate of formation of B is set to zero, the concentration of B is zero. Therefore, the correct answer is not listed among the given options.
