Experimental Rate Law Question3. In the gas-phase reaction between methane (CH,) and diatomic sulfur (S,):CH (g) + 2S,(8)- H,S(g) + CS,(g)Several experiments were performed at 550 C at various starting concentrations of CH, and S,.The results are shown in the table below:ExperimentInitial [CH.] (M)Initial [S2] (M)Initial Rate of Reaction (M/s)0.0900.1401.39 X 10220.0900.2202.18 x 10230.1450.1402.23 X 10-2Determine the rate law and the rate constant for this reaction.Integrated Rate Law Question4. Iodine-131 (I) is a radioactive isotope frequently used in medicine as a diagnostic andtherapeutic tool to treat thyrotoxicosis and thyroid cancer. It decays via a first-order process toxenon-131 (“Xe) emitting a high energy B-particle. If the initial concentration of I in alaboratory sample is 1.24 x 10” M and 9.60 x 10# M after 3.00 days, what is the rate constant?What is the half-life for the decay process?131 1 – B + Xe
