Apotential energy diagram is shown. what is the total change in enthalpy of this reaction?

a. 25 kj
b. 30 kj
c. 35 kj
d. 55 kj

A. 25 kJ

Explanation:

In this case,

Energy of products = 55 kJ

Energy of reactants = 30 kJ

Therefore;

Total enthalpy change = 55 kJ - 30 Kj

                                     = 25 kJ

The reaction is endothermic since the energy of products is greater than the energy of the reactants.

A

Explanation: 55 KJ - 30 KJ = 25 KJ

Just took the test

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  

i think its 100

i hope this !
