When a chemical change occurs, there are two types of ways heat can be involved. In an endothermic reaction, more heat enters the reaction than leaves. In an exothermic reaction, more heat leaves the reaction than enters.

One of the ways that enzymes speed chemical reaction is?
They are organic catalysts. All catalysts will speed up a reaction by lowering the activation energy of the reaction, or the energy required to break certain atoms apart so that they can be reformed to make new products.
Describe the ways that energy is converted between forms during the light reactions?
Light reaction is the first stage of the photosynthetic reaction when the sunlight is converted into the chemical energy in the form of ATP and NADPH. ... The electron transport chain produces the NADPH and ATP via ATP synthase. Thus, the light energy gets converted to the chemical energy during light reaction.
What are two ways that chemical reaction between substances affect chemical bonds?
3j
How does the catalyst and inhibitors affect the rate of chemical reaction?
Catalyst ensures that the activation energy of the molecules is lowered so there is effective collisions,and it does this in two ways;the transition and absorbtion states but inibitors even raises the activation energy and causes in effective collisions.
Do catalysts speed up a chemical reaction or slow it down?
A catalyst works by providing a reaction route with a lower activation energy. An inhibitor slows a reaction and can work in several ways, for instance by tying up one of the reactants. We also use the term when we say catalyst inhibitor, which is something which binds to the active sites on a heterogeneous catalyst.
What are the ways that heat takes part in a chemical changes?
Heat can be involved in a chemical reaction that is endothermic(absorbs heat) or that is exothermic(releases heat)
What are two ways heat can be involved in chemical change?
heat can be one of the products as in a combustion reaction and it can be used as a catalyst
What speeds up in chemical reaction?
There are numerous ways to affect the speed of a chemical reaction. They are add a catalyst, increase the concentration of reactants, increase surface area of reactants, increase pressure, and increase the energy in the environment around the reaction.
One of the ways that enzymes speed chemical reaction is?
They are organic catalysts. All catalysts will speed up a reaction by lowering the activation energy of the reaction, or the energy required to break certain atoms apart so that they can be reformed to make new products.
What are 5 ways to identify chemical reaction?
production of a gas formation of a precipitate change in color transfer of energy (heat and/or light)

What ways can a catalyst affect a chemical reation?
A catalyst affects a reaction by speeding it up. A catalyst, remember, does not participate as a reactant or product in the reaction. It facilitates the reaction by lowering its activation energy, making the reaction easier to happen.
What are uses of chemical energy?
Some ways chemical energy is used are: A battery turns chemical energy into electric energy which can be used for electric supplies. A candle turns chemical energy in wax into light. Car engines turn chemical energy into mechanical energy.
What are the five ways to know that chemical reaction happened?
don't know
