CO(g)+2H2(g)->CH3OH(g) How many moles of each reactant are needed to produce 3.60 X 10^2g of CH3OH?
Explain why selectivity in isocratic HPLC system ideally should not depend on eluent composition. Use thermodynamic derivation to support your explanation.
The rule works particularly well for weakly interacting molecules, such as those of a noble gas, but not so well for water among other substances. Assuming the rule is exact, estimate the molar enthalpy of evaporation for Argon (in kJ/mol), whose ..
