The effectiveness factor for large value of Thiele modulus [L√(K/D1)] of a solid catalysed first order reaction is equal to (where, L = length of the reactor, cm, D1 = diffusion co-efficient, cm2/second) ?
Correct answer: B
Explanation
For a large Thiele modulus, the effectiveness factor approaches 1/Thiele modulus. The Thiele modulus is L√(K/D1).
