Observe the following reaction, 2 A + ...

Observe the following reaction,
`2 A + B to C`
The rate of formation of C is ` 2.2 xx 10 ^(-3) mol L ^(-1) "mtextn"^(-1),` then rate of disappearance of A is

A

`2.2 xx 10 ^(-3) "mol L"^(-1) "min"^(-1)`

B

`1.1 xx 10 ^(-3) "mol L" ^(-1) "min" ^(-1)`

C

`4.4 xx 10 ^(-3) "mol L" ^(-1)"min" ^(-1)`

D

`5.5 xx 10 ^(-3) "mol L"^(-1) "min "^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`2 A + B to C`
Rate of reaction,
`= - (1)/(2) (d [A])/( dt) =- (d[B])/( dt) = (d[C])/(dt)`
` therefore - (d[A])/(dt) = 2 (d [C])/(dt)`
`= 2 xx 2.2 xx 10 ^(-3)`
`= 4.4 xx 10 ^(-3) "mol L"^(-1) "min"^(-1)`
