The gas phase decomposition of ethylamine produces ethane and ammonia according to the following equation:-(adsbygoogle = window.adsbygoogle || []).push({});

C_{2}H_{5}NH_{2}(g) → C_{2}H_{4}(g) + NH_{3}(g)

The following total pressures were found for this reaction at 500°C 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 P_{0}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?
