Given the oxygen dissociation curves, which of the following statements are correct? HbF loads oxygen at lower p O 2 pO2 than does HbA in the presence of 2,3‑BPG. 2,3‑BPG only weakly interacts with HbF. 2,3‑BPG is an allosteric activator of HbA. The allosteric effects of 2,3‑BPG are homotropic. Purified HbA has a higher o

A.

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
