Two balloons are filled with an equal volume of air. One is put in the refrigerator for an hour, while the other is heated in a slightly warm oven. Identify which balloon is which, and explain why.

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
