The conversion of methyl isonitrile to acetonitrile in the gas phase at 250 °C CH3NC(g)--CH3CN(g) is first order in CH3NC with a rate constant of 3.00x103 s If the initial concentration of CHNC is 8.48x10 M, the concentration o f CHNC will be 2.32x10 M after 3.644 s have passed. Incorrect For a first order reaction of the form Aproducts, the equation that relates concentration to time is In [A] = In [A],-kt. In this case: [CH3NC-2.32x10-2 M k-3.00x10s Substituting into the above equation gives In [2.32x101-In(8.48x103)-(3.00x10 sts) t 432 s 1:38 PMM

Explanation / Answer

[CH3NC]0 is the initial concentration.

[CH3NC]t is the concentration of CH3NC after time t.

For first order reaction,

ln [CH3NC]0 / [CH3NC]t = K1 * t

ln (8.48 * 10^-2 / 2.32 * 10^-2) = 3.00 * 10^-3 * t

ln (8.48 / 2.32 ) = 3.00 * 10^-3 * t

t = 432 s (answer)
