Explanation: The given reaction, (2C(s) + SiO_2(s) \rightarrow Si(s) + 2CO(g)), shows that carbon (C) is able to displace silicon (Si) from silicon dioxide (SiO2), resulting in the formation of silicon and carbon monoxide. This indicates that carbon is more reactive than silicon. The reaction also demonstrates that silicon can be extracted by reducing silicon dioxide with carbon. Therefore, the position of silicon in the reactivity series is below that of carbon, as silicon is less reactive than carbon and can be displaced by carbon in certain chemical reactions. :3
