Given below are two statements : Statement-I : Methane and steam passed over a heated Ni catalyst produces hydrogen gas. Statement-II : Sodium nitrite reacts with \(\mathrm{NH}_{4} \mathrm{Cl}\) to give \(\mathrm{H}_{2} \mathrm{O}, \mathrm{N}_{2}\) and NaCl . In the light of the above statements, choose the most appropriate answer from the options given below :

(A) Both the statements I and II are correct

(B) Both the statements I and II are incorrect

Given below are two statements :

Statement-I : Methane and steam passed over a heated Ni catalyst produces hydrogen gas.
Statement-II : Sodium nitrite reacts with

NH_{4} Cl

to give

H_{2} O, N_{2}

and NaCl .
In the light of the above statements, choose the most appropriate answer from the options given below :

(A)Both the statements I and II are correct✓ Correct
(B)Both the statements I and II are incorrect
(C)Statement I is incorrect but Statement II is correct
(D)Statement I is correct but Statement II is incorrect

Answer: (A)

Solution

Statement I is correct:

CH_{4} (g) + H_{2} O (g) Ni 1270 K CO (g) + 3 H_{2} (g)

. This is the steam reforming of methane, producing hydrogen gas.

Statement II is correct:

NaNO_{2} (aq) + NH_{4} Cl (aq) \to N_{2} (g) + NaCl (aq) + 2 H_{2} O (ℓ)

. This reaction produces nitrogen gas, water, and sodium chloride.

Both statements are correct.
