What else can I help you with?
You may normally expect a slow reaction if a low activation energy is required?
Yes, reactions with low activation energies typically proceed at a slower pace because only a small amount of energy is needed to initiate the reaction. This means that fewer collisions between reactant particles will have enough energy to overcome the activation energy barrier, resulting in a slower overall reaction rate.
Is the activation energy for chemical reactions in living things high or low?
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
Which of the following combinations will generally produce the slowest reaction?
The combination of a low temperature and a high activation energy will generally produce the slowest reaction. A low temperature slows down the kinetic energy of the reacting molecules, while a high activation energy requires more energy for the reaction to occur.
Energy required to start chemical reaction?
Energy required for a reaction can vary. Depending on the atom it changes. The element will be more reactive if it has a low 1st ionization energy since it requires less energy to react. The most reactive element in Francium since it has the lowest 1st ionization energy level. If an element has a high electro-negativity then it will also be able to react with little energy.
How does the complete filling of a subshell affect E?
The complete filling of a subshell results in increased stability due to the formation of a full set of orbitals with paired electrons, according to the Pauli exclusion principle. This stable configuration typically corresponds to a low-energy state for the atom or ion.
Does endothermic have high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.

Energy of activation is?
The energy need to activate something depends on what is being activated. These energies can range from high to low.

What is activation energy how is the rate constant of a reaction related to its activation energy?
In chemistry, activation energy is a term introduced in 1889 by the Swedish scientist Svante Arrhenius that means the minimum energy that must be input to a chemical system with potential reactants to cause a chemical reaction. Activation energy may also be defined as the minimum energy required to start a chemical reaction.The activation energy of a reaction is usually denoted by Ea and given in units of kilojoules per mole
What factors are responsible for the formation of oceanic patterns?
Heat and energy from low lattitudes
What Activation energy play in a chemical reaction?
It indicates how likely a reaction might be, but there are no hard rules. Low activation energy indicates that the reaction is likely to take place spontaneously. In most cases, the reaction must be exothermic as well. There are lots of exceptions to these simple rules. For any reaction to occur, the reactants must gain at least the activation energy.
The activation energy for the chemical reaction in living thing is high or low?
The activation energy for chemical reactions in living things is typically low compared to non-biological reactions. This is because living organisms rely on enzymes to catalyze reactions, lowering the energy barrier needed for the reaction to occur. This allows for faster and more efficient processing of biological molecules.
Why is the activation energy pictured as a hill in two diagrams?
The activation energy is represented as a hill in reaction energy diagrams to illustrate the energy barrier that must be overcome for a chemical reaction to occur. The reactants must acquire enough energy to surpass this barrier before they can form products. The height of the hill represents the activation energy required for the reaction to take place.
