52. which results in the graph in figure 7-12 are more likely to be accurate, those represented by line a or line b? why?
53. what could account for the differences in lines a and b in the graph
54.

The accurate line represented by line b because during such experiment ( osmosis or mass transfer) there would be a time where the system be in equilibrium meaning that that the net movement will be zero. In line B at time starting 15 min equilibrium is reached no further movement is attained beyond it.

correct answer is a. and d.
