JEE Main 5 April 2024, Shift 1, Chemistry Q63

Question 63 of 90 in this shift, Chemistry question 3 of 30, Section A.

The following reaction occurs in the Blast furnace where iron ore is reduced to iron metal Fe2O3(s)+3CO(g)⇌Fe(l)+3CO2(g)\mathrm{Fe_2O_{3(s)} + 3CO_{(g)} \rightleftharpoons Fe_{(l)} + 3CO_{2(g)}} Using the Le-chatelier's principle, predict which one of the following will not disturb the equilibrium.
  1. (1)Removal of CO
  2. (2)Removal of CO2\mathrm{CO_2}
