Argon and methane are absorbed from nitrogen into liquid ammonia at 2523 k and 175.0 atm. feed rate of gas is 100.0 kmol/h. feed gas contains 0.020 mol% ar and 0.130 mol% methane. outlet gas contains 0.0008 mol% methane. entering liqud ammonia is pure. operate with l/v-26.0. assume l and v flow rates are constam equilibrium data for methane is, partial pressure methane = 3600 atm and the partial pressure for argon = 7700 atm
a. find the outlet mole fraction of methane in the liquid
b. find the number of equilibrium stages required.
c. find the outlet mole fraction of argon in the gas.

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

explanation:

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

it's all four options.
