Consider a gas-phase reaction: A+2BC that takes place in a packed-bed reactor (PBR) with a catalyst volume of 0.2 L. The feed rate of A is 0.1 mol/s and the feed rate of B is 0.2 mol/s. The reaction rate constant is 0.01 L/(mol s) and the pressure drop across the catalyst bed is 2 bar. What is the conversion of A at the exit of the reactor? (Hint use Ergun equation) [15] this question was asked i saw the answers but when i punch them on a calculator it gives me a different answer. from first answer where we were calculating superficial velocity, the written answer is 7,6m/s but when punch on calculator it gives me 152,789m/s. please help me understand
