General Principles and processes of Isolation of Elements
normal
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 |
