Calculate the percentage yield of 1M of potassium chromate (50 ml) and Lead (II) nitrate 1 mol (50ml)
Reaction yield = 16.160 gThe rate law for the reaction, 2NO(g) + O2(g) ? 2NO2(g), is found to be: rate of reaction = k [?NO]2?[O2?]2. The first, fast step is
2NO(g) -- N2O2 (g) (note: this arrow is also in reverse)
Which best represents the rate equation for the rate-determining step of this reaction?
Chose from these answer choices:
rate of reaction = k1 [NO]rate of reaction = k2 [N2O2]rate of reaction = k3 [N2O2][O2]rate of reaction = k3 [NO2][O2]
