Answer from: alexabdercmur

The balanced equation for the reverse reaction would be

2SO_3 (g) < ----- 2SO_2 (g) + O_2 (g)

Reversible reactions

They are reactions that proceed in opposing directions - that is, reactants to products and vice versa.

The equilibrium system between sulfur dioxide gas, oxygen gas, and sulfur trioxide gas can be represented as:

2SO_2 (g) + O_2 (g) < --- 2SO_3 (g)

Thus, the reverse reaction would be:

2SO_3 (g) < ----- 2SO_2 (g) + O_2 (g)

Answer from: speedyblackmann

This is a missing part of your question:
The equilibrium system between sulfur dioxide gas, oxygen gas, and sulfur trioxide gas is given.
So you need the equilibrium balanced equation of SO2, O2, SO3 reaction:
First, we will start with the original equation which is not balanced yet (to understand how we get it):
SO2 + O2 ↔ SO3
Here the number of O atom is not equal at the to sides
So we will start to balance our equation by make the number of O atom equal each other on both sides:
So we will start to put 2SO3 instead of SO3
and put 2SO2 instead of SO2 to balance also the S atom on both sides
So we will get this:
2SO2(g) + O2(g) ↔ 2SO3(g) (This is our equilibrium balanced equation)
know we have a number of O atom equals on each side = 6
and the sulfur equals on each side = 2

Answer from: Quest

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

Yes i think so not 100 percent sure though
