Be sure to answer all parts. The first-order rate constant for the reaction of methyl chloride (CH,CI) with water to produce methanol (CH,OH) and hydrochloric acid (HCI) is 3.32 × 1010at 250C. Calculate the rate constant at 45.5°C if the activation energy is 116 kJ/mol. x10 (Enter your answer in scientific notation.)

Cyclobutane, C4H8, consisting of molecules in which four carbon atoms for a ring, decomposes when heated to give ethylene. C4H8(g)  →  2C2H4(g) The reaction is first order. In an experiment, the initial concentration of cyclobutane was (3.500x10^-3) M. After heating at 450 °C, for (5.55x10^2) s, this was reduced to (2.6090x10^-3) M. What was the concentration of cyclobutane after a total of (1.008x10^3) s? Express your answer to three significant figures. Just enter the number  (e.g. 2.48x10^-4) and the unit.

Potentially Useful Reference Information -Ea J R = 8.314 k = A· e RT mol·K Calculate the rate constant (k) for a reaction where a 0.1 M first order reactant and a 0.3 M second order reactant result in a rate of 4.5 x 103 M/sec. Report your answer with one significant figure; you do not need to include any units, just the value of k. The molarities given are the initial concentrations for each reactant.

Under certain conditions the rate of this reaction is zero order in dinitrogen monoxide with a rate constant of 0.0022 Ms: 2N,0 (g) - 2N, (g) +0, (g) Suppose a 400. mL flask is charged under these conditions with 500. mmol of dinitrogen monoxide. After how much time is there only 250. mmol left? You may assume no other reaction is important. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits. 10 Ar
