Question

0.5 moles of gas A and x moles of gas B exert a pressure of 200 P a in a container of volume 10 m 3 at 1000 K . Given, R is the gas constant in JK - 1 mol - 1 , x is:, 4 + R 2 R, 2 R 4 + R, 4 - R 2 R, 2 R 4 - R

According to the ideal gas equation: PV = nRT 200 × 10 = ( 0 .5 + x ) R × 1000 2 = 0 .5 R + xR x = 2 - 0 .5 R R = 4 - R 2 R
