Agitation affects reaction rate by increasing the amount of collisions the atoms make with one another, therefore speeding up the reaction rate.
Agitation increase the time of settling.
Stirring improve the reaction rate.
decrease the energy requirement of reaction, which increase the rate of reaction itself
Reaction rate increase when the concentration increase.
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.
That depends on the order of the reaction. If the reaction is zero order with respect to a reactant, then changing the concentration will have no effect on rate. If it is first order, then doubling the concentration will double the rate. If it is second order, then doubling the concentration will quadruple the rate.
Stirring improve the reaction rate.
The effect of temperature on the rate of diastase reaction is that it acts as a catalyst. Higher temperatures will speed up the reaction.
When an enzyme is saturated the amount of substrate added no longer as an effect on the rate of the reaction.
decrease the energy requirement of reaction, which increase the rate of reaction itself
increasing the concentration increases the rate of the reaction
increasing the concentration increases the rate of the reaction
increasing the concentration increases the rate of the reaction
increasing the concentration increases the rate of the reaction
An increase in temperature speeds up the reaction rate.
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical 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.
A catalyst speeds up the rate of a reaction.
