Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
A Bronsted acid donates a proton and a Bronsted base accepts a proton.
$H C O_{3}^{-} + H^{+} ⟶ H_{2} C O_{3}$ Bronsted base
$H C O_{3}^{-} ⟶ C O_{3}^{2 -} + H^{+}$ Bronsted acid
Since, $H C O_{3}^{-}$ can donate a proton to form $C O_{3}^{2 -}$ and can accept a proton to form $H_{2} C O_{3}$ , it can act as a Bronsted acid as well as a Bronsted base. Hence both assertion and reason are correct and reason is the correct explanation for assertion.

Q. Assertion: The impurities such as

{SiO}_{2}

present in iron ore is removed by

{CaCO}_{3}

.

Reason:

CaO

formed by decomposition of

reacts with

{SiO}_{2}

to form slag.

Assertion (A) Order of the reaction can be zero or fractional.

Q. Assertion: The compressibility factor for

H_{2}

and

H e

(1 + \frac{P b}{R T})

Reason: The compressibility factor for
