Assertion : Extraction of iron metal from iron oxide ore is carried out by heating with coke.Reason : The reaction ${\text{Fe}}_2{\text{O}}_{3(s)}\to {\text{Fe}}_{(s)}+3/2{\text{O}}_{2(g)}$ is a spontaneous process.

Iron is extracted by heating oxide ore with coke (which acts as a reducing agent) and flux. The direct decomposition of ${\text{Fe}}_2{\text{O}}_3$ to Iron and Oxygen is NOT a spontaneous process. Instead, ${\text{Fe}}_2{\text{O}}_3$ is reduced to $\text{FeO}$ and then to $\text{Fe}$ at high temperatures ($800^{\circ }\text{C}$ to $1000^{\circ }\text{C}$). The assertion is true, but the reason is false.
