Which among the following is an essential chemical reaction for the manufacture of pig iron? Correct Answer Fe2O3 + 3C → 2Fe + 3CO

Coke is reacted with hematite at a high temperature through a furnace. As air reacts with coke CO and heat is generated as iron oxide is reduced, molten iron gathers at the base of the furnace.

For a reaction, the extent of reaction equation is Ni = Nio + ϒVi is Where: Ni = Moles of species I present in the system after the reaction occurs Nio = Moles of species I present in the system when the reaction starts Vi = Stoichiometric coefficient for species i in the specified chemical reaction equation ϒ = Extent of reaction
Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is
