all chemical reaction has to be thought of to be there
Which factor usually increases the rate of reaction?
Stirring a mixture
If you need to multiply the following reaction by choice to be an intimate reaction to have some small problem what will be the final value for the entropy overreaction used for the intermediate react?
To determine the final entropy change for a reaction when multiplied by a choice, you would typically apply the principle of additivity of entropy. If you multiply a reaction by a factor, the change in entropy for the overall reaction will also be multiplied by that same factor. Therefore, if you have the standard entropy change for the original reaction, you would multiply that value by the factor you used to scale the reaction to find the final entropy change for the intermediate.
What factor in reaction rate is related to the amount of reactants?
This is the concentration of reactants.
How dies activation affect the progress of a reaction?
Activation energy is the minimum energy required for a chemical reaction to occur. Higher activation energy means that fewer molecules will have enough energy to react, slowing down the reaction rate. Conversely, lowering the activation energy, often through catalysts, increases the number of successful collisions between reactants, speeding up the reaction progress. Thus, activation energy is a critical factor in determining how quickly a reaction proceeds.

What factor might make an endothermic reaction spontaneous?
An endothermic reaction can be spontaneous if the increase in entropy (disorder) of the system is large enough to overcome the energy input required for the reaction to occur.
When one fission reaction instigates more than on fission reaction it is called?
A runaway chain reaction.It is called super criticality, with KEffective > 1.When one fission reaction instigates more than one or more fission reactions it is called a Chain Reaction.KEffective is the neutron multiplication factor which is an indication of whether a reaction is stable (=1), increasing (>1), or decreasing (

What element can control the condition at which a reaction occurs?
The activation energy is the energy required to initiate a chemical reaction and is a key factor in controlling the conditions at which a reaction occurs. Lowering the activation energy through the use of a catalyst can accelerate the reaction rate. Additionally, factors such as temperature, concentration, and pressure can also influence the rate of a reaction.
Which factor in excessive amounts contributes to the development of cancer cells growth and division?
binary fission
What causes a chain reaction in uranium?
Each atom, when split, releases one or more neutrons. Those neutrons go on to destabilize and split other atoms. This is the "chain reaction" we talk about. The multiplication factor, known as Keffective represents the rate of increase in reactivity. If Keffective is 1, then, on average, one atom's split results in one neutron that splits one atom.
If you multiply the following reaction by 2 to be an intermediate reaction in a Hess's law problem what would be the final value for the enthalpy of reaction you use for this intermediate reaction?
When you multiply a reaction by a factor, you also multiply the enthalpy change by the same factor. Therefore, if you multiply the reaction by 2, the final value for the enthalpy of reaction for the intermediate reaction will also be multiplied by 2.
A factor that speeds up a chemical reaction?
catalysts
How do you calculate n factor in an reaction?
first check out the total charge and the no of moles and then the n factor
The amount of energy needed to start a chemical reaction is called what?
The energy required is called the activation energy. The minimum amount of energy needed to start a chemical reaction is given by the formula Ea=-RT*ln(k/A). R is the universal gas constant, T is temperature in Kelvin, k is the reaction rate coefficient and A is the frequency factor.
