General Principles and processes of Isolation of Elements
medium
List $-I$ shows reaction involve in metallurgy of $Pb$ (lead) and List $-II$ shows name of processes. Match List $-I$ with List $-II$ and select correct code for your answer.
| List $-I$ | List $-II$ | ||
| $(P)$ | $PbS + 2PbO\xrightarrow{\Delta }3Pb + S{O_2} \uparrow $ | $(1)$ | Smelting |
| $(Q)$ | $PbS + \frac{3}{2}{O_2}\xrightarrow{\Delta }PbO + S{O_2} \uparrow $ | $(2)$ | Self reduction |
| $(R)$ | $PbC{O_3}\xrightarrow{\Delta }PbO + C{O_2} \uparrow $ | $(3)$ | Calcination |
| $(S)$ | $PbO+C\xrightarrow{\Delta }Pb + CO \uparrow $ | $(4)$ | Roasting |
