Be sure to answer all parts. Take all the thermodynamic data from your textbook. Assume the data do not vary with temperature.

(a) Calculate ΔSuniv for the reaction H2O2(l) → H2O2(g) at 171.0°C. Enter your answer in the box provided. J/K · mol

(b) Is the reaction spontaneous, nonspontaneous, or an equilibrium process? Select the best single answer. spontaneous nonspontaneous an equilibrium process

(c) The reaction NH3(g) + HCl(g) → NH4Cl(s) is spontaneous in the forward direction at room temperature. Determine the temperature at which it is no longer spontaneous in the forward direction.

(d) Determine the boiling point of Br2, in degrees C
