Question

Previous Answers Correct Because this pressure is relatively high, the molecules are close together, making intermolecular attraction more pronounced Therefore is likely that the true pressure will differ from this ideal value. The van der Waals equation will give you a more accurate value for pressure. Part c To prevent tank rupture during deep-space travel. an engineering team is studying the effect of temperature on gases confined to small volumes. What is the pressure of 4.00 mol of gas D measured at 251 C in a 1.75-L container assuming real behavior? Express your answer with the appropriate units.

Explanation / Answer

A/c to ideal gas equation PV = nRT

P = nRT/ V

P= 4 x 0.0821 x 524/ 1.75 (T = 251+273 = 524 K, R = 0.0821 Lit.atm.

P= 98.34 atm
