Q.

Which of the following statements is true if red hot iron is reacted with steam?

1. It forms triferric tetra oxide and releases hydrogen gas

2. It's a reversible reaction if hydrogen isn't separated

3. Iron is more reactive than zinc

Q.

During manufacture of Hydrogen through the Bosch Process, separation of carbon dioxide can be done by:

1. mixing the solution with excess steam

2. passing the solution through cold water under 30 atm

3. passing the solution through the ammoniacal cuprous chloride solution

4. passing the solution through caustic potash solution

Q.

When steam is passed over red-hot coke it forms:

1. Syngas

2. $C{O}_2+H_2$

3. Water gas

4. $CO+H_2$

Q. Which catalyst is used in the Bosch process when water gas is mixed with excess steam?

1. $C{r}_2{O}_3$
2. $F{e}_2{O}_3$
3. $K_{2}O$
4. $CuO$

Q. Identify the catalyst 'y' used in the given reaction.

Reaction 1:
$C\left(redhotcoke\right)+\underset{\text{Water gas}}{H_{2}O}$(g) $\stackrel{1273K}{⟶}$ $CO\left(g\right)+H_2\left(g\right)$

Reaction 2: $CO\left(g\right)+H_2\left(g\right)+H_{2}O\left(g\right)$ $\stackrel{y\left(catalyst\right)}{⟶}C{O}_2\left(g\right)+2H_2\left(g\right)$

1. $F{e}_2{O}_3$
2. $V_2{O}_5$
3. $\text{Ziegler Natta Catalyst}$
4. $\text{Raney Ni}$

1. industrial
2. producer
3. natural
4. water
