Question

What is the rate of formation of ‘C’ in the following reaction?

A + 2B → 2C

विकल्प

• Same as the rate of consumption of A

• Half the rate of consumption of B

• Twice the rate of consumption of A

• 3/2 times of the rate of consumption of B

Answer 1

Twice the rate of consumption of A

Explanation:

A + 2B → 2C

Rate of reaction 

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

Rate of formation of C, `(d[C])/dt`

`= -2 (d[A])/dt = -(d[B])/dt`

Therefore, the rate of formation of C is twice the rate of consumption А.
