Question

For a reaction 1/2 A ⇒ 2B, rate of disappearance of A is related 't o the appearance of B by the expression:

विकल्प

• `(-d[A])/(dt) = 4(d[B])/(dt)`

• `(-d[A])/(dt) = 1/4(d[B])/(dt)`

• `(-d[A])/(dt) = 1/4(d[B])/(dt)`

• `(-d[A])/(dt) = (d[B])/(dt)`

Answer 1

`(-d[A])/(dt) = 1/4(d[B])/(dt)`

Explanation:

Rate = `1/(1/2) = (d[A])/(dt) = 1/2 (d[B])/(dt) = (-d[A])/(dt) = 1/4 (d[B])/(dt)`
