Question

A reaction X 2 ( g ) → Z ( g ) + 1 2 Y ( g ) exhibits an increase in pressure from 150 mm to 170 mm in 10 minutes. The rate of disappearance of X 2 in mm per minute is, 2 mm per minute, 8 mm per minute, 4 mm per minute, 6 mm per minute

MARKS App · Accepted Answer

Total pressure = 150 - x + x + x 2 = 150 + x 2 = 170 x = 40 mm Rate of disappearance of X 2 = 40 10 = 4 mm/min.
