What is the minimum pressure in kpa that must be applied at 25 °c to obtain pure water by reverse osmosis from water that is 0.227 m in sodium chloride and 0.078 m in magnesium sulfate? assume complete dissociation for electrolytes.

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
