The rate of a certain reaction is given by the following rate law: rate=k H2 | I2| *[H:]L] Use this information to answer the questions below. What is the reaction order in H,? What is the reaction order in I,? ? What is overall reaction order? At a certain concentration of H2 and I2, the initial rate of reaction is 34.0 M / s. What would the initial rate of the reaction be if the concentration of H2 were halved? Round M S your answer to 3 significant digits. The rate of the reaction is measured to be 0.530 M/ s when [H2] = 1.4 M and [I2] = 0.21 M. Calculate the value of the - 1 - 1 k = |M •S rate constant. Round your answer to 2 significant digits.

Butadiene, C,H, (used to make synthetic rubber and latex paints) dimerize C3H12 with a rate law of rate = 0.014 L/mo[• s [CH]². If the remäining %3D concentration of CaH, is 0.028 M after 0.35 hours, what is the initial concentration of C4H, in molar? Report a numerical value with 3 decimal places, without units.

5. You studied the chemical reaction, 2NO2(g) → 2NO(g) + O2(g), at 25°C by monitoring the concentration of NO2(g) as a function of time and constructed the following graph. y= 0.5408x + 125.0 R2=0.998 Time (s) What is the rate constant for this reaction at 25°C? Include the proper units. (W/T) [(3)ONI/T

Be sure to answer all parts. The rate law for 2 NO(g) + O2(g)→ 2 NO2(g) is rate = k[NO]°[O2l. %3D The following mechanisms have been proposed: I. 2 NO(g) + O2(g)→ 2 NO2(g) II. 2 NO(g) = N½O2(g) [fast] N,O2(g) + O2(g) → 2 NO,(g) [slow] III. 2 NO(g) = N,(g) + O2(g) [fast] N2(g) + 2 O2(g) → 2 NO2(g) [slow] (a) Which of these mechanisms is consistent with the rate law? Check all that apply. I. II. III. None of the above (b) Which of these mechanisms is most reasonable? I. II. III.
