True or false of thermodynamics?

1.An open system allows the transfer of heat to the surroundings.


2.Thermodynamics describes the direction in which a reaction will proceed.


3.The system includes all that we are not focusing on.


4.A spontaneous reaction requires that the enthalpy of the universe decrease.


5.Spontaneous reactions can be slow.





Thanks everyone.True or false of thermodynamics?
1) A system is open when heat and mass may flow across the boundary. True


2) Thermodynamics is the study of heat flow, and will describe the direction of a reaction. True


3) A system is the things that you only want to look at. False


4) False Entropy of the system and the surrounding must increase for a spontaneous reaction.


5) True Spontaneous reactions are not dependent on the reaction rate. The speed of a reactions is not determined by spontaneity.
