i have a couple of questions Which of the following would not be considered spontaneous?a.cooling a cup of coffee at room temperatureb.ice melting at room temperaturec.compression of gas to fill a tired.water flowing downhillThe molar enthalpy of combustion for one mole of propane is -2202 kJ. There are two ways to express this reaction using chemical equations. Write both types of chemical equations for the forward exothermic reaction. Then draw an enthalpy diagram similar to diagram (a) above. Include reactants, products, and the heat of the reaction. Take a digital picture of your diagram and upload it below.
