The rate equation for the reaction 2A + B → C is found to be rate = k [A] [B]
The correct statement in relation to this reaction is that the
(AIEEE 2004)
  • a)
    unit of k must be s-1
  • b)
    t1/2 is a constant
  • c)
    rate of formation of C is twice the rate of disappearance of A
  • d)
    unit of k is L mol-1 s-1
Correct answer is option 'D'. Can you explain this answer?

The rate equation for the reaction 2A + B C is found to be rate = k [A...
2A + B → C
Rate = k [A] [B]
It represents second order reaction.
Thus, unit of k is L mol-1 s-1.
Hence, (a) is false,
t1/2 is dependent of concentration but not constant.
Hence, (b) is false.

Thus, (c) is also false,
unit of k = conc1-x time-1
By rate law n = 2
Thus, unit is cone-1 time-1
(L mol-1 s-1 if concentration in mol L-1 and time in second)
