The diagram shows the potential energy changes for a reaction pathway. (10 points) Part 1: Describe how you can determine the total change in enthalpy and activation energy from the diagram, and if each is positive or negative.

Part 2: Describe how the curve will look if the reaction was exothermic. Be sure to mention changes in the potential energies of the reactants and products and the sign changes of the enthalpy.

i believe it is 40–40–20%

explanation:

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

the dissolution of polymer can be thermodynamically described in 2 steps.

catya your not at all which answer i've seen you do this on another question!
