A gas mixture containing CH3 fragments, C2H6 molecules, and an inert gas (He) was prepared at

600.0 K

with a total pressure of

5.42 atm.

The elementary reaction

CH3 + C2H6

→

CH4 + C2H5


has a second-order rate constant of 3.00

×

104/M

·

s. Given that the mole fractions of CH3 and C2H6 are 0.000850 and 0.000760, respectively, calculate the initial rate of the reaction at this temperature.
