Q. 2. Suppose an irreversible reaction occurring on the surface of a solid catalyst, where both reactants A and B are present in the gaseous phase. Solid Catalyst A (g) + B (g) C (g), Rate of reaction step is defined as r'' = R''CACB. Gas contains only two components A and " K" B, where mole fraction of A in bulk gas is 99 % and mole fraction of B in bulk gas is 01 %. Combine the mass transport rate of gaseous film at the surface of solid catalyst with reaction rate and determine the overall rate of reaction
