Question

Acetaldehyde, CH3CHO, will decompose into methane and carbon monoxide according to

CH3CHO (g) -> CH4 (g) + CO (g)

At 450C the rate of consumption of CH3CHO is measured to vary with the concetration of CH3CHO raised to the power 1.5.

With a CH3CHO concentration of 0.222M, the rate of consumption of CH3CHO at 450C is measured to be 3.33*10-3 M/s. Calculate the rate of production of carbon monoxide when the concentration of CH3CHO has fallen to 0.111M.

Express your answer in M/s:

Answer 1

(1.18)*10^-3

Answer 2

1.18*e-3
