How does pressure affect the chemical equilibrium?

If the pressure is increased, the position of equilibrium moves in the direction of the fewest moles of gas. Therefore, if the pressure is increased, the position of equilibrium will move to the right and more methanol will be produced.

Can a combustion reaction be in equilibrium?

Combustion terminates when equilibrium is achieved between the total heat energies of the reactants and the total heat energies of the products. Most reactions terminate when what is called thermal equilibrium has been attained—i.e., when the energy of the reactants equals the energy of the products.

What does the fuel react with during a combustion reaction?

Combustion is a high-temperature exothermic (heat releasing) redox (oxygen adding) chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion cannot take place in an atmosphere devoid of oxygen.

What will disturb the equilibrium of a chemical reaction?

Systems at equilibrium can be disturbed by changes to temperature, concentration, and, in some cases, volume and pressure; volume and pressure changes will disturb equilibrium if the number of moles of gas is different on the reactant and product sides of the reaction.

How will decreasing pressure affect the equilibrium position in a reversible reaction?

Decreasing the pressure moves the equilibrium to the side with the most molecules. This reduces the effects of the change because the pressure increases as the number of molecules increases.

What are the factors on which the combustion of fuel depends?

Fuel combustion rate depends on three factors: the rate of the chemical reaction of the combustible fuel constituents with oxygen; the rate at which oxygen is supplied to the fuel (the mixing of air and fuel); and. the temperature in the combustion zone.

Why is combustion considered to be a chemical change?

because it is start from chemical and when it is change they use oxygen and carbon dioxide.

How is combustion A chemical reaction?

So, combustion is a chemical reaction when a fuel is burned to release energy. A fuel is a substance which is burned to release energy in a useful way. And the final thing we need to know is oxidation. This is when a substance gains an oxygen atom in a reaction and this happens during combustion.

How can chemical equilibrium be manipulated?

A chemical system at equilibrium can be temporarily shifted out of equilibrium by adding or removing one or more of the reactants or products. The concentrations of both reactants and products then undergo additional changes to return the system to equilibrium.

When pressure is increased to the equilibrium system?

When there is an increase in pressure, the equilibrium will shift towards the side of the reaction with fewer moles of gas. When there is a decrease in pressure, the equilibrium will shift towards the side of the reaction with more moles of gas.
