For the reaction A + B → 2C at a given temperature, the rate of disappearance of A is found to be 10^-² moles L^–1 sec^–1. Calculate (i) rate of disappearance of B and (ii) rate of formation of C.

Solution

For a given reaction
A + B → 2C
we have given
the rate of disappearance of A is 10^-² moles L^–1 sec^–1
(ii)
rate of expression can be written as

$\frac{- d [A]}{dt} = \frac{- d [B]}{d t}$

since rate of disappearance of A is given to be 10^-² moles L^–1 sec^–1thus
rate of disappearance B 10^-² moles L^–1 sec^–1

(iii)
$\frac{d [A]}{dt} = \frac{1}{2} \frac{d [C]}{d t} a s g i v e n \frac{d [A]}{d t} = 10^{- 2} m o l e s L^{- 1} s e c^{- 1} t h u s 10^{- 2} m o l e s L^{- 1} s e c^{- 1} = \frac{1}{2} \frac{d [C]}{d t} \frac{d [C]}{d t} = 2 x 10^{- 2} m o l e s L^{- 1} s e c^{- 1}$
for Ans. (i) 10^–2 mol L^–1 sec^–1 (ii) 2 x 10^–2mole L^–1 sec^–1
