Cоnsider the fоllоwing list of definitions аnd stаtements: I) Molecules in gаs state can be assumed to have mass but no volume II) Objects in physical contact will reach thermodynamic equilibrium III) The average kinetic energy of the molecules in a system is proportional to the absolute temperature (temp in Kelvin) IV) Spontaneous reactions increase the entropy of the universe V) Molecules in the gas phase are in constant random motion VI) The enthalpy of a reaction is equal to the sum of the enthalpy of reaction of any composite reactions VII) Energy is neither created nor destroyed only transferred between types VIII) All collisions between gas phase molecules complete transfers all energy IX) Some energy in an energy transfer is given over to entropy X) Gas phase molecules are so far apart from each other they have essentially no interactions with each other Which of the statements above are assumptions of kinetic molecular theory?
