Heat - increases it
Increased stirring - increases it
larger surface area - increases it
catalyst - usually increases it
and the reverse of the above slows the reaction down
Catalyst alter chemical rate of reaction
Yes, the rate constant can change with concentration in a chemical reaction.
The Reaction Rate
This is called reaction rate.
To calculate the initial rate of reaction in a chemical reaction, you measure the change in concentration of a reactant over a specific time interval at the beginning of the reaction. This change in concentration is then divided by the time interval to determine the initial rate of reaction.
Enzymes alter the equilibrium of a chemical reaction by lowering the activation energy required for the reaction to occur, thus speeding up the rate at which the reaction reaches equilibrium. This is achieved by stabilizing the transition state of the reaction, making it easier for the reactants to form products.
A catalyst alters the rate of a chemical reaction.
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
A catalyst alter rate of reaction by lowering the activation
speeds it up or starts it
A catalyst doesn't undergo a chemical change during a chemical reaction.
The rate constant of a chemical reaction generally increases with temperature. This is because higher temperatures provide more energy for molecules to react, leading to a faster reaction rate.
