Given the reaction A(g) + B(g) ⇌ C(g) + D(g), consider the following situations:

i. You have 1.3 M A and 0.8 M B initially.
ii. You have 1.3 M A, 0.8 M B, and 0.2 M C initially.
iii. You have 2.0 M A and 0.8 M B initially.
After equilibrium has been reached, order i–iii in terms of increasing equilibrium concentrations of D. Explain your sequence. Then give the order in terms of the increasing equilibrium concentration of B and explain.
