What is the rate expression for physical absorption of a gas A to a liquid based on two film theory? (Where, kAg is the gas film mass transfer coefficient and kAl is the liquid film mass transfer coefficient) |
| A. | -r<sub>A</sub> = ( frac{p_A- H_A C_A}{ frac{1}{a} + frac{1}{k_{Al}a}} ) |
| B. | -r<sub>A</sub> = ( frac{p_A- C_A}{ frac{1}{k_{Ag} a} + frac{1}{k_{Al} a}} ) |
| C. | -r<sub>A</sub> = ( frac{p_A- H_A C_A}{ frac{1}{k_{Al}a}+ frac{1}{k_{Al}a}} ) |
| D. | -r<sub>A</sub> = ( frac{H_A C_A}{ frac{1}{k_{Al} a}+ frac{1}{k_{Al}a}} ) |
| Answer» D. -r<sub>A</sub> = ( frac{H_A C_A}{ frac{1}{k_{Al} a}+ frac{1}{k_{Al}a}} ) | |
