Which of the following will change the equilibrium constant? a. changing temperature, b. nothing changes the value of keq, c.varying the ititial concentration of reactants, d. varying the initial concentration of products, e. changing the volume of the reaction vessel
Assuming that DHo and DSo hardly change with temperature, determine the temperature in K at which the spontaneity of this reaction changes.
One way to recrystallize a solute from a solution is to change the temperature. Another way is to evaporate solvent from the solution. A 340 g sample of a saturated solution of KNO3 in water is prepared at 25.0.
how will you use the known compounds that are out in the lab to help you find the identity of your unknown compounds
You have a container of pure O2 and N2 at 298K and 1atm pressure. Calculate delta G mixing if 12 mol of pure N2 are added to the mixture of 15 mol of O2 and 15 mol of N2.
The reaction of 0.130 moles of a metal with an acidic aqueous solution in a calibrated calorimeter causes the temperature to increase by 49.0°C.
dissolving one mole of a non-volatile solute in 4 moles of a volatile solvent. If the vapor pressure of the pure solvent is 20 torr, what will be the vapor pressure of the solution.
