Which is the reactant for the reaction that is powered by sun hitting photo system?
In photosynthesis, the reaction powered by sunlight in photosystems primarily involves water (H₂O) as the reactant. When sunlight hits the photosystems, it energizes electrons in chlorophyll, leading to the splitting of water molecules. This process generates oxygen (O₂) as a byproduct and provides the necessary electrons and protons for the synthesis of glucose.

Which is a reactant for the reaction that is powered by sun hitting photo system 2?
In photosynthesis, the reaction powered by sunlight hitting Photosystem II primarily uses water (H₂O) as a reactant. When light energy is absorbed, it drives the splitting of water molecules into oxygen, protons, and electrons. This process is crucial for generating energy in the form of ATP and NADPH, which are utilized in subsequent reactions of photosynthesis.
What would happen when a reactant is added to a system at equilibrium?
When a reactant is added to a system at equilibrium, the concentration of that reactant increases, causing the system to shift in the direction that consumes the added reactant according to Le Chatelier's principle. This shift will favor the forward reaction, leading to the production of more products until a new equilibrium is established. As a result, the concentrations of products will increase while the concentrations of the original reactants will adjust back to equilibrium levels.
What does Le chatellers principle say about upsetting a system at equilibrium?
Le Chatelier's principle states that if a system at equilibrium is disturbed by a change in concentration, temperature, or pressure, the system will shift in a direction that counteracts the disturbance to restore a new equilibrium. For example, if the concentration of a reactant is increased, the system will favor the forward reaction to consume the added reactant. Similarly, if the temperature is increased in an exothermic reaction, the system will shift to favor the endothermic direction to absorb the excess heat. This principle helps predict how a chemical system will respond to changes in conditions.
When is a reaction said to be endothermic?
A reaction is said to be endothermic when it absorbs heat from its surroundings, which means that heat is a reactant in the reaction. This results in a decrease in the temperature of the surroundings.
What would happen to a system at equilibrium of more of one compound in a reaction were added?
If the added substance is a reactant, the equilibrium shifts toward products. If it is a product, it moves towards reactants.
Which is a reactant for the reaction that is powered by hitting photo system II?
ADP
How is heat included in the equation of an exothermic reaction?
Heat is written as a product of the reaction (apecs answer)
Adding products to systems at equililbrium will do what?
In general, adding product to a system at equilibrium will push the reaction toward the reactant side.
What will happen when a reactant is added to a system at equilibrium?
The equilibrium of the system will be upset.

How factors affect rates of physical change?
-Reactant Concentration • The greater the concentration of reactants (the more particles per unit volume), the greater will be the number of effective collisions per unit time, and therefore, the reaction rate will generally increase. • For zero order reactions, however, the reaction rate is not dependent on the concentration of reactants. Increasing the reactant concentration will have no effect on the rate. -Temperature • The reaction rate will increase as the temperature of the system increases. As the temperature increases, the reactant molecules have more energy. They thus find it easier to climb the energy barrier to the reaction (the activation energy). -Solvent • The reaction rate will increase as the temperature of the system increases. As the temperature increases, the reactant molecules have more energy. They thus find it easier to climb the energy barrier to the reaction (the activation energy).
According to Le Chatelier principle what happens if heat is added to a system?
The reaction shifts to remove the heat APEX
Describe what can happen to the reaction rate of a system that is heated then cooled?
Heating a system typically increases the reaction rate as the molecules have more energy to react. Cooling the system will usually slow down the reaction rate as the molecules have lower energy levels, leading to fewer successful collisions between reactant molecules.
Is carbon a product or reactant?
Carbon can be both a reactant and a product in chemical reactions. It can act as a reactant by combining with other elements to form compounds, or it can be produced as a product when carbon-containing compounds are broken down or converted into other substances.

How does a system at equilibrium respond to the addition of more reactant or Product?
Le Chetalier's Principle states "If to a system in equilibrium, a change is applied, the system will react to tend to negate that change" - or the substance of that statement. So if you add product, the system will tend to go to the reverse reaction and produce more reactant. Vice Versa. If more reactant is added, the system reacts to make more product to restore equilibrium.
