How does the rate of endothermic reactions change as temperature is increased?
As temperature increases, the rate of endothermic reactions also increases. This is because higher temperatures provide more energy for the reaction to occur, leading to a faster reaction rate.
How can photosynthesis be increased by increasing the temperature?
Temperature affects living things mainly by affecting the rate of chemical reactions. These are catalysed by enzymes, which are speeded up by increasing the temperature. The Calvin cycle is a series of chemical reactions, so increasing the temperature increases the rate of reactions in the Calvin cycle and so increases the rate of photosynthesis.
How does changing the temperature of solutions affect the rate of reactions?
In most cases, increasing the temperature increases the rate of the reaction.
How does temperature aff ect the rate of chemical changes?
An increase in temperature increases the rate of most, but not all, chemical reactions.
How the difference in the movement of atoms at two different temperatures affects the rate of most chemical reactions?
Generally at high temperature the rate of chemical reactions is greater.
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 is the speed of a chemical reaction is increased by?
Most effectively increased speed by temperature increase and adding a catalyst ( = enzymes in biological reactions. Further measures: raising concentration of reactants, grinding solids, mixing, for some reactions: put in light scource
What would cause the greatest decrease in the rate of chemical reaction?
For most reactions, the lowering of the temperature of the reactants.
The rate at which a rock in a streambed dissolves would not be increased by .?
The rate at which a rock in a streambed dissolves would not be increased by decreasing the temperature of the water because lower temperatures generally slow down chemical reactions, including the dissolution process.
How are rate constants temperature dependent in chemical reactions?
Rate constants in chemical reactions are temperature dependent because as temperature increases, the molecules move faster and collide more frequently, leading to a higher likelihood of successful reactions. This relationship is described by the Arrhenius equation, which shows that rate constants increase exponentially with temperature.
Increased temperature will increase?
rate of solution
How does temperature speed affect the reaction?
For endothermic reactions the increase in temperature increases the K.E of the molecules and numbers of effective collisions per unit volume per unit time among reacting molecules becomes increased so rate of the reaction also becomes increased.
