Reaction rate can change due to factors such as temperature, concentration of reactants, presence of catalysts, and surface area of reactants. Increasing temperature generally increases reaction rate by providing more energy for molecular collisions, while higher reactant concentrations and larger surface areas promote more frequent collisions between reactant molecules. Catalysts can also lower activation energy and increase reaction rate by providing an alternative pathway for the reaction to proceed.
The Reaction Rate
This is called reaction rate.
Increasing the temperature will increase the reaction rate, as will finding a suitable catalyst.
In general (but not always), the reaction rate will increase with increasing concentrations. If the reaction is zero order with respect to that substance, then the rate will not change.
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
Heat can change the rate of reaction
Yes, the rate constant can change with concentration in a chemical reaction.
The Reaction Rate
The concentration of the reactants decreases.
The concentration of the reactants decreases.
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.
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.
This is called reaction rate.
A catalyst
a chemical reaction
Increasing the temperature will increase the reaction rate, as will finding a suitable catalyst.
In general (but not always), the reaction rate will increase with increasing concentrations. If the reaction is zero order with respect to that substance, then the rate will not change.
