MHT CET 2024 Chemistry question
Find the value of Q from following equations. (i) kJ (ii) kJ (iii) kJ
Answer: (A)
Solution
Equation (i) is the direct formation of from carbon. Apply Hess's law: carbon can be burned in two steps, first to CO (ii) and then CO to (iii). Adding (ii) and (iii): \tfracO_2\tfracO_2$ → CO
