Extra Gedit. Effectivaness Factor for a Langmwer$-$Hibshelwood Rate Form

Consider the following reaction that occurs in a porous slab cataly st and the associated rate expression.

Alongrightarrow Prodacts

$y=K_{C_M}\frac{K_A{C}_A}{1+K_A{C}_A}$

The pranutar $C_m$ is the toter concentration of active sitos and is constant. This rate expression arises when gas$-$phase A adoure onto the catalyst surpace and the reaction is first order in the adsorbed A concentiration.

Derive an expression for the effectiveness factor for the case where the surface of the slab is exposed to a constant ges$-$phose concintratios CAs.You man adopt tho same general paranciturs for the catalyst geometry and applicable particulans as descineed above in Problem $2$
