Temperature can increase and decrease the rate of reactions. Heat increases, while cold decreases the rate of reaction. With the help of enzymes.
What else can I help you with?
How does changing the temperature of solutions affect the rate of reactions?
In most cases, increasing the temperature increases the rate of the reaction.
Which has higer rate of reaction the one with higher temperature or not?
The greater the temperature, the faster the rate of reaction. This is due to the fact that increasing temperature increases the activation energy, which is the amount of energy needed to get a reaction started.
What factors increases the reaction rate by increasing particle speed?
Increasing the temperature of the system leads to higher particle speeds, increasing the chances of collisions between reactant molecules. This in turn increases the reaction rate as a higher proportion of collisions will have sufficient energy to overcome the activation energy barrier.
How is the rate of reaction affected when the temperature increases?
As the temperature increases, the reaction time decreases.
What effects does the concentration of reactions have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
What effect does the concentration on reactants have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
What effect does the concentration of reactants have on the rate of reaction?
increasing the concentration increases the rate of the reaction
What effect does the concentrate of reactants have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
What effect of concentration of reactants have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
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.
Is temperature essential in determining the reaction rate?
yes, as the reaction rate increases with increase in the temperature
How does concentration affect the rate of a chemical reaction?
Increasing the concentration of the reactants increases the rate of the reaction.
