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 3.00×10-3 s-1. If the initial concentration of CH3NC is 4.30×10-2 M, the concentration of CH3NC will be 8.30×10-3 M after s have passed.

548s = t

Explanation:

A first-order reaction has as general equation:

Where is the concentration of the reactant in the time t, is the initial concentration of the reactant, k is rate constant and t is time. Replacing with values of the problem:

-1.65 = -3.00x10⁻³s⁻¹×t

548s = t

I hope it helps!

The ability to do work

Explanation:

Energy refers to the ability to carry out work.It is measured in Joules (J).Energy may exist in different forms such as potential energy when a body is at rest, kinetic energy when the body is in motion, etc.Energy can neither be created nor destroyed, however, it can be transformed from one form to another. For example, chemical energy may be transformed into mechanical energy or other forms of energy.
