In a closed system, matter cannot enter or leave the system, but energy can still be exchanged with the surroundings. Chemical reactions in a closed system will reach equilibrium, where the rates of the forward and reverse reactions are equal and the concentrations of reactants and products remain constant. The total amount of matter in the system will not change during a reaction in a closed system.
A container or system must be closed to prevent the exchange of matter with the surroundings, ensuring that all relevant interactions and reactions occur within a defined environment. This isolation allows for the establishment of equilibrium, where the rates of forward and reverse processes equalize, resulting in stable concentrations of reactants and products. In an open system, external influences can disrupt this balance, making it impossible to achieve true equilibrium. Therefore, maintaining a closed system is essential for accurate observations and calculations in thermodynamics and chemical reactions.
Yes, it's true.
most chemical reactions dealing with enzymes preform best in a certain small temperature range, so increased or decreased temperatures could result in the slowing down of reactions
Yes, once the equilibrium of a system is disturbed, the system will react to establish a new equilibrium. This involves shifts in the forward and reverse reactions to minimize the disturbance and reach a stable state again.
True. Some enzymes are able to catalyze multiple types of chemical reactions due to their flexible active sites that can accommodate different substrates. This versatility allows them to participate in various metabolic pathways within an organism.
No. In a closed system, the mass of the products should equal the mass of the reactants.
yes. true.
At equilibrium, the rates of the forward and reverse reactions are equal, but chemical reactions are still occurring.
Yes, it's true.
No, not all chemical reactions are reversible. Some reactions are irreversible, meaning they cannot easily be reversed to reform the original reactants.
True
This is true. Energy is required to begin all reactions.
True
One thing that is true for all exergonic reactions is that the reaction continues with a net release of what is called free energy. Exergonic reactions are chemical reactions.
True. The minimum Gibbs free energy is not attained by a semipermeable membrane, as the membrane itself does not participate in any chemical reactions that could lower the system's overall free energy. The minimum free energy is achieved through chemical reactions occurring within the system.
Yes.
