When a reaction take place at low temperature than high temperature?
At low temperatures, reactions typically occur more slowly because the kinetic energy of the molecules is reduced, leading to fewer effective collisions between reactants. Additionally, some reactions may become thermodynamically favored at lower temperatures if they are exothermic. In contrast, at high temperatures, the increased kinetic energy can enhance reaction rates and allow for endothermic reactions to occur, but may also lead to side reactions or decomposition of reactants. Thus, temperature significantly influences both the rate and the direction of chemical reactions.
Which change will increase the rate of an endothermic reaction in the forward direction?
Increasing the temperature will enhance the rate of an endothermic reaction in the forward direction. Since endothermic reactions absorb heat, providing additional heat energy will shift the equilibrium toward the products, thereby increasing the reaction rate. Additionally, increasing the concentration of reactants or using a catalyst can also help speed up the reaction.
How particle collisions that affect the rate of chemical reactions?
When the number of particle collisions increase the rate of chemical reactions also increase.
What are the 5 factors that can affect the rate of chemical reactions?
5 factors that can affect the rate of chemical reactions are temperature, pressure, concentration, stirring, catalysts.
What physical factors control the rate of chemical reactions?
Physical factors that control the rate of chemical reactions include temperature, pressure, concentration of reactants, and surface area of the reactants. Temperature influences the kinetic energy of particles, pressure affects the collision frequency of molecules, concentration determines the number of reactive collisions, and surface area determines the contact area between reactants.
What influences The rate and direction of reactions?
Stability of the compound or compounds.
Is speed the rate of change?
NO! It is the rate of reactions!

At optimum light intensity which atmospheric gas most directly influences the rate of photosynthesis?
Carbon dioxide (CO2) is the atmospheric gas that most directly influences the rate of photosynthesis under optimum light intensity, as it is needed as a substrate for the Calvin cycle, one of the key reactions in photosynthesis. Increasing the concentration of CO2 can usually lead to an increase in the rate of photosynthesis up to a certain point.
What is the reduction potential of water and how does it impact chemical reactions?
The reduction potential of water is -0.83 volts. This means that water has a tendency to lose electrons in chemical reactions. This can impact reactions by influencing the direction and rate at which electrons are transferred between reactants, ultimately affecting the overall outcome of the reaction.
What is the education rate of Belgium?

What has the largest rate constant k?
exploding dynamite
What is rate in theater?
In theater, "rate" often refers to the pace or tempo of a performance, including how quickly or slowly lines are delivered and actions occur. It influences the overall mood and emotional impact of a scene. Additionally, "rate" can also pertain to the evaluation or assessment of a production, which can include audience reactions, critical reviews, or box office performance.
Which is not a factor that influences your appetite?
basal metabolic rate
Do enzymes decrease the rate of chemical reactions?
No, they Increase the speed of chemical reactions
