Reaction I : `3C` ( natural graphite) + `SoO_(2)overset("heat")tounderset(+2CO)(SiC)overset(2500^(@)C)to C` (graphite) +`Si` Reaction II : `SiO_(2)+2CtoSi+2CO` Reaction I is used in production of synthetic graphite, whereas Reaction II is used in extraction od silicon.A. Reaction I - `SiO_(2)` in excess , Reaction II - `SiO_(2)` in excessB. Reaction I - `C` in excess , Reaction II - `SiO_(2)` in excessC. Reaction I - `SiO_(2)` in excess , Reaction II - `C` in excessD. It does not matter. |
