Question
Fluid A has a PCO_2 65 mmHg and the CO_2 of 5.6 mg/L PCO_2 55 mmHg and a CO_2 content of 6.6 mg/L. Based on this information, which of the following statements is true A) CO_2 will diffuse for Fluid A Fluid B because of the concentration gradient. B) CO_2 will diffuse from Fluid B to Fluid A because of the concentration gradient. C) CO_2 will diffuse for Fluid A to Fluid B because of the partial pressure gradient D) CO_2 will diffuse for Fluid B to Fluid A because of the partial pressure gradient. E) there will be no net diffusion because the partial pressure gradient is in the opposite direction as the concentration gradient and they cancel each out.Explanation / Answer
B)Co2 will diffuse from fluid B to fluid A because of the concentration gradient. In the diffusion the mass transfer occurs from high concentration to the low concentration. Hence concentration gradient plays more important role. In this case fluid B has high concentration than fluid A so mass will be transfered from high to low concentration.
Case E will be true when the system will be gas liquid and in equilibrium which will follow the Henry's law.
