Problem
Consider the reaction: A(g) ⇌ 2B(g). The graph plots the concentrations of A and B as a function of time at a constant temperature.
The figure shows the concentration as a function of time. Concentration is measured from 0 to 1 mole per liter on the y-axis and time is measured on the x-axis. There are two curves on the plot. Curve A starts at 1 mole per liter, then decreases to approximately 0.6 moles per liter, and then becomes a straight horizontal line. Curve B starts at 0 moles per liter, increases with the same speed as curve A to 0.8 moles per liter, and then becomes a straight horizontal line. These curves cross at the concentration about 0.65 moles per liter.
