The gas phase decomposition of ethylamine produces ethane and ammonia according to the following equation:-

C2H5NH2 (g) → C2H4 (g) + NH3 (g)

The following total pressures were found for this reaction at 500C with an initial pressure of pure ethylamine equal to 55 mm Hg.

Ptotal (mm Hg) time (min)
55 0

64 2

72 4

89 10

93 12


If P0 is the initial pressure of reactant and ptotal is the total pressure at time t, show how the the partial pressure of reactant remaining at time t can be found.

Can anyone give hint to me how to start to solve this question?

is it i have to apply avogadro's law?

That, plus stoichiometry.
