The question was posed to me in a national level competition.

This interesting question is from Material Balances Problems Involving Multiple Units topic in division The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering

Answer 1

The correct option is (d) 959.2 Kg/hr

To elaborate: Material balance for air: 0.94*1000 = 0.98*C, => C = 959.2 Kg/hr.
