The respiration of a suspension of yeast cells was measured by determining the decrease in pressure of the gas above the cell suspension. The apparatus was arranged so that the….

## Calculate the compressibility factor for C, if one mole of it occupies 0.4 ltr at 300 K and 40 atm.

The mass of molecule *A *is twice that of molecule *B*. The root mean square velocity of molecule *A *is twice that of molecule *B*. If two containers of equal volume have same number of molecules, the ratio of pressure *PA*/*PB *will be

(a) 8 : 1 (b) 1 : 8 (c) 4 : 1 (d) 1 : 4

Calculate the compressibility factor for C, if one mole of it occupies 0.4 ltr at 300 K and 40 atm. Comment on the result.

(a) 0.40, C is more compressible than ideal gas.

(b) 0.65, C is more compressible than ideal gas.

(c) 0.55, C is more compressible than ideal gas.

(d) 0.62, C is more compressible than ideal gas.
