A hypothetical reaction X2 + Y2 → 2XY follows the following mechanism:
X2 → X + X ... fast
X + Y2 → XY + Y … slow
X + Y → XY … fast
The order of the overall reaction is
X2 → X + X ... fast
X + Y2 → XY + Y … slow
X + Y → XY … fast
The order of the overall reaction is
- a)2
- b)3/2
- c)1
- d)0
Correct answer is option 'B'. Can you explain this answer?

A hypothetical reactionX2+ Y2→2XY follows the following mechanism...
Given Mechanism:
- X2→X + X (fast)
- X + Y2→XY + Y (slow)
- X + Y→XY (fast)
Rate-determining step:
The slow step in the reaction mechanism is the rate-determining step, which is X + Y2→XY + Y.
Rate Law:
The rate law for this step is rate = k[X][Y2].
Overall Reaction Order:
The overall reaction order is the sum of the individual reaction orders in the rate-determining step.
- The reaction order with respect to X is 1 (from X in the rate law).
- The reaction order with respect to Y is 1 (from Y2 in the rate law).
Therefore, the overall reaction order is 1 + 1 = 2/2 = 3/2.
Therefore, the correct answer is option B.
- X2→X + X (fast)
- X + Y2→XY + Y (slow)
- X + Y→XY (fast)

A hypothetical reactionX2+ Y2→2XY follows the following mechanism...
Rate = k[X][Y2]
Rate =
Thus, order of the reaction
But the rate law expression cannot be expressed in terms of a reaction intermediate.
Rate =
Thus, order of the reaction
