It depends. A higher temperature will speed up an endothermic reaction, but slow down an exothermic reaction.
The temperature of the system
Temperature change affects the rate of a chemical reaction by altering the kinetic energy of the colliding particles. As temperature increases, particles move faster, leading to more frequent and energetic collisions, which enhances the likelihood of overcoming the activation energy barrier. Conversely, lower temperatures slow down particle movement, resulting in fewer collisions and a reduced reaction rate. Thus, temperature is a critical factor in determining how quickly a reaction proceeds.
An increase in temperature speeds up the reaction rate.
Factors affecting the reaction rate:- Concentrations of the reactants- Temperature- Pressure- Sirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
the experimental rate law of a simple reaction A->B+C is v=k[A].calculate the change in the reaction rate when:(a) the concentration of A is tripled (b) the concen-tration of A is halved
The temperature of the system
Analyzing the reaction rate vs temperature graph can provide insights into how temperature affects the speed of a chemical reaction. The graph can show the relationship between temperature and reaction rate, such as how increasing temperature can generally increase the rate of reaction due to more collisions between reactant molecules. Additionally, the graph can help identify the temperature at which the reaction rate is maximized, known as the optimum temperature.
rate of reaction depends on the amount of reactants
Force of gravity. The temperature of Mars. The number of ships in the harbour. The weight of a penny.
How the concentration of the reactants affects the rate of a reaction
An increase in temperature speeds up the reaction rate.
Temperature affects the rate constant in a chemical reaction by increasing it. As temperature rises, 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 the rate constant is exponentially dependent on temperature.

if the reaction is exothermic (creates heat) then adding heat will cause the reaction to run in the reverse direction if the reaction is endothermic (requires heat) then heat will speed it up

yes, as the reaction rate increases with increase in the temperature
