Rate of reaction over a finely crushed catalyst of radius of 0.5 mm was measured as 10.0 mole/sm3 catalyst. Temperature is 400 K and pressure is 105 Pa and mole fraction of reactant in the gas is 0.1. Find the rate for a catalyst of pellet radius of 3mm. (Assume ηC = 1 for small catalyst).

• A. 7.01 mole / m3s
• B. 7.03 mole / m3s
• C. 7.05 mole / m3s
• D. 7.07 mole / m3s
