For this reaction: ΔG⁰>0.
Balanced chemical reaction A(g) ⇌ (g)
ΔG° indicates that all reactants and products are in their standard states.
ΔG° = R·T·lnK.
ΔG° is Gibbs free energy
T is the temperature on the Kelvin scale
R is the ideal gas constant
The equilibrium constant (K) is the ratio of the partial pressures or the concentrations of products to reactants.
Gibbs free energy (G) determines if reaction will proceed spontaneously, nonspontaneously or in equilibrium processes.
If K < 1, than ΔG° > 0.
Reactants (in this example A) are favored over products (in this example B) at equilibrium.

The most important hydrogen bonding is the DNA.
Radiant energy is energy contained in electromagnetic waves. These include visible light, infrared, radio waves, ultraviolet and microwaves. ... Chemical energy is energy stored in chemical bonds between atoms.
Photosynthesis is the transformation of radiant energy to chemical energy. Plants take in water, carbon dioxide, and sunlight and turn them into glucose and oxygen. Called photosynthesis, one of the results of this process is that carbon dioxide is removed from the air.

A combustion reaction is a reaction that reacts in the presence of oxygen molecules. Methane will release -3115 kJ/mol of heat.
<h3>What is a combustion reaction?</h3>
A combustion reaction includes the reaction between the chemical reactant and oxygen molecule to produce the product. The combustion reaction between methane and oxygen is given as:
CH₄(g) + 2O₂ (g) → CO₂(g) + 2H₂O (l), ΔH = -890 kJ/mol
The stoichiometry coefficient from the reaction gives 1 mole of methane releases -890 kJ/mol enthalpy.
So, 3.5 moles methane will release = 3.5 × -890 = -3115 kJ/mol
Therefore, -3115 kJ/mol of heat is released.
