In order to determine order/rate constant of any gaseous reaction pressure data at constant volume and temperature can be analysed. For a gaseous reaction occurring in a rigid vessel at 300 K following data was observed.
`2A(g) rarr 3B(g) +2C(g)`
`{:(,"Time (min)",,"10 min",,"30 min",,infty time),(,"Pressure increase (mm of Hg)",,"30 mm",,52.5 min,,"60 min"):}`
What will be the total increase in pressure 20 min after the reaction?

Options

A. 45 mm of Hg
B. 50 mm of Hg
C. 55 mm of Hg
D. 40 mm of Hg

Answer

A
