Question

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
(a) rate of formation of C is twice the rate of disappearance of
A
(b) t₁/₂ is a constant
(c) unit of k must be s⁻¹
(d) value of k is independent of the initial concentrations
of A and B

Answer 2

The correct statement in relation to this reaction is that the (d) value of k is independent of the initial concentrations  of A and B.

1. The unit of K is $mol^{-1}s^{-1}$ so option c is incorrect
2. The rate of formation is the 1/2 the rate of disappearance not double so option a is also incorrect
3. t₁/₂ depends upon the concentration so it is also not constant
4. the value of k is independent of the initial concentrations of A and B this is the only correct option
