Mr. Wells told his students that the Water cycle DOES have a clear beginning and a clear end. Mrs. Meador disagrees with him and says the Water Cycle DOES NOT have a clear beginning and end. Who do you agree with and 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?
