A certain reaction has delta H^degree = -35.4 kJ and delta S^degree = -85.5 J/K. Use this information to answer the questions below:
1.) Is the reaction exothermic or endothermic?
2.) Does the reaction lead to an increase or decrease in the disorder of the system?
3.) Calculate Delta G^degree for the reaction at 298 K.
4.) Is the reaction spontaneous at 298 K under standard conditions?
