Question

6) When a spontaneou s, endothermic reaction occurs at constant temperature and pressure, the entropy change of the surroundings is: a) impossible to tell b) positive c) negative d) zero a) ΔG > 0 One finds that the equilibrium constant for a particular reaction increases with increasing temperature. Assuming that the standard reaction enthalpy and entropy are temperature independent, this means that: a) The standard reaction enthalpy is less than zero 8) b) The standard reaction entropy is greater than zero c) The standard reaction entropy is less than zero d) The standard reaction enthalpy is greater than zero 9) Upon dissolving salt into a mixture of ice and water at equilibrium, the temperature of the mixture will: a) impossible to tell b) increase c) decrease d) stay the same 10) During the isothermal expansion of an ideal gas: a) w--q b)q0 c) q<w
