FREE Expert Solution

We’re being asked to solve graphically the instantaneous rate in M/s at t = 5000 s based on the data for the isomerization of methyl isonitrile (CH3NC) to acetonitrile (CH3CN).


An instantaneous reaction rate is the rate at a particular moment in the reaction and is usually determined graphically and can be calculated as:


rate=  t

Δ[  ] = change in concentration
Δt = change in time


To do so, we will make a graph of the concentration of CH3CN in M (y-axis) vs. time in s (x-axis)
