The conversion of methyl isonitrile to acetonitrile in the gas phase at 250 °C CH3CN(g) is first order in CH3NC with a rate constant of 3.00×10^-3 s-1. If the initial concentration of CH3NC is 5.45×10^-2 M, the concentration of CH3NC will be 1.56×10^-2 M after s have passed.

The concentration of will be after 416 seconds have passed.

Explanation:

Expression for rate law for first order kinetics is given by:

where,

k = rate constant =

t = age of sample = ?

a = let initial amount of the reactant =

a - x = amount left after decay process =

The concentration of will be after 416 seconds have passed.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
