Brylee Noble · Answer 1

The reaction absorbs 8100 J of energy from the surroundings as it proceeds.

Jake Dunlap · Answer 2

For the reaction to take place the energy of the reactants must reach to the energy level of the products:

we have 900 J in the reactants and 9000 J for the products so the reactants need 8100 J to reach to the value of energy of products (900 + 8100 = 9000)

So the correct answer is C. The reaction absorbs 8100 J of energy from the surroundings as it proceeds.
