For the reaction, 2A + B → 3C, rate of disappearance of A is 0.3 M/s in a certain time interval.What is the average rate of appe

andrezito [222]

Answer:

E) rate of appearance of C = 0.45 M/s

rate of the reaction = 0.15 M/s

Explanation:

2A + B → 3C

Writing rate law for the reaction:

Rate of reaction = - $\frac{1}{2}$ $\frac{d[A]}{dt}$ = - $\frac{d[B]}{dt}$ = $\frac{1}{3}$ $\frac{d[C]}{dt}$ → equation 1

Given that the rate of disappearance of A is 0.3 M/s

⇒ - $\frac{d[A]}{dt}$ = 0.3 M/s

⇒Rate of reaction = - $\frac{1}{2}$ $\frac{d[A]}{dt}$ = $\frac{1}{2}$ ×0.3 M/s

⇒Rate of reaction = 0.15 M/s

From equation 1, $\frac{d[C]}{dt}$ = - $\frac{3}{2}$ $\frac{d[A]}{dt}$ = $\frac{3}{2}$ ×0.3 M/s

⇒ $\frac{d[C]}{dt}$ = 0.45 M/s

or the rate of appearance of C = 0.45 M/s
