How is the rate of reaction affected when the temperature increases?
As the temperature increases, the reaction time decreases.
Why does the temperature of a reaction increases reaches a maximum and then decreases?
The maximum temperature is attained when the reaction is completed.
The favorability or spontaneity of a reaction increases when during the course of a reaction?
The favorability or spontaneity of a reaction increases when the overall entropy of the system increases, or when the free energy of the system decreases. This can happen when reactants are in a more disordered state, when the system achieves greater stability, or when the reaction releases heat.
What changes of temperature on rate of reaction?
The rate of reaction increases with increasing temperature. When the temperature is increased, the kinetic energy of the reacting particles hence the frequency of effective collisions are also increased. Hence the rate of reaction is faster.
What effect does a catalyst have?
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.
How is the rate of reaction affected when the temperature increases?
As the temperature increases, the reaction time decreases.
For which of reaction listed below will gibbs free energy always be positive?
Guys watch out the question, if your question end with positive then the answer will be An endothermic reaction that decreases in entropy. If the question end with negative then its An exothermic reaction that increases in entropy--APEX hope this help
Why does the temperature of a reaction increases reaches a maximum and then decreases?
The maximum temperature is attained when the reaction is completed.
What is a re-dox reaction?
A reaction in which electrons have been transferred from one atom to another .
What happen to atoms in an oxidation-reduction reaction?
The oxidation state of one atom increases while another decreases.
The favorability or spontaneity of a reaction increases when during the course of a reaction?
The favorability or spontaneity of a reaction increases when the overall entropy of the system increases, or when the free energy of the system decreases. This can happen when reactants are in a more disordered state, when the system achieves greater stability, or when the reaction releases heat.
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
How does increasing temperature increases rate reaction?
Temperature can increase and decrease the rate of reactions. Heat increases, while cold decreases the rate of reaction. With the help of enzymes.
What causes the reaction rate to decreases as the reaction progresses?
The concentration of the reactants decreases.
What is the difference between an activator and a deactivator in organic chemistry?
In organic chemistry, an activator is a molecule that increases the rate of a chemical reaction, while a deactivator is a molecule that decreases the rate of a chemical reaction.
Why does physisorption decreases with increasing temperature?
physisorption is an exothermic reaction.so according to le chatlier's principle,as temperature increases,backward reaction is favoured
Decreasing the temperature of a reaction decreases?
According to collision theory, decreasing the concentration of the reactants in a chemical reaction decreases the frequency of the collisions between reactants, and therefore decreases the rate of the reaction.
