Answer 1

The Correct Option is D

The correct answer is (D) : A-IV, B-III, C-II, D-I
Cobalt catalyst $\to$ Methanol production
Syn gas $\to$ Coal gasification
$\left(C_{(\text{Red hot coke})}+H_{2}O(g)\to CO+H_2\right)$
Nickel catalyst $\to$ Water gas production
Brine solution $\to$ Production
$($ aq. $NaCl)\left(\begin{array}{c}{H}_2\to \text{Cathode}\\ C{l}_2\to \text{anode}\end{array}\right)$

Answer 2

Cobalt catalyst is widely used in the production of methanol. This is because cobalt helps in facilitating the hydrogenation of carbon monoxide to methanol in the presence of syngas (a mixture of carbon monoxide and hydrogen). The reaction typically takes place at high pressures and temperatures, making cobalt an essential component in the catalytic process. Thus, the correct match for cobalt catalyst is (A-IV), methanol production. 

Syngas, primarily a mixture of carbon monoxide and hydrogen, is crucial in the process of coal gasification. In coal gasification, coal is reacted with oxygen and steam at high temperatures to produce syngas. This syngas is then used for various applications, including the production of chemicals like methanol and synthetic fuels. Hence, the correct match for syngas is (B-III), coal gasification. 

Nickel catalysts are highly effective in the water gas shift reaction, where carbon monoxide and water vapor react to produce carbon dioxide and hydrogen. This reaction is crucial in producing hydrogen gas in the chemical industry. Nickel, with its ability to catalyze this reaction at moderate temperatures, is widely used for water gas production. Therefore, the correct match for nickel catalysts is (C-II), water gas production. 

Brine solution is commonly used in the production of chlorine and hydrogen gases through the electrolysis of saltwater. In this process, the brine solution is subjected to electrolysis, which splits the sodium chloride (NaCl) into sodium hydroxide (NaOH), chlorine gas \(Cl_2\), and hydrogen gas \(H_2\). Thus, the correct match for brine solution is (D-I), chlorine and hydrogen production.
