Exothermic reactions release heat energy during the reaction. By carrying out these reactions at low temperatures, it helps to control the rate of reaction and prevents overheating or loss of control over the reaction. It also reduces the risk of side reactions and improves the overall yield of the desired product.
What else can I help you with?
what refers to reactions that give off energy as they occur?
Such reactions are called Exothermic reactions. Their change in enthalpy is negative. Such reactions are favorable at low temperature.
What are chemical reactions that release energy in the abscence of oxygen called?
Anaerobic reactions, like fermentation or anaerobic respiration, occur in the absence of oxygen and release energy by breaking down glucose or other molecules into simpler compounds. These reactions are important for organisms that live in environments with low oxygen levels.
How do Enzymes permit low temperature reactions?
Enzymes permit low-temperature reactions by stabilizing the transition state of a reaction, reducing the activation energy required for the reaction to occur. This allows the reactions to proceed more readily at lower temperatures. Enzymes achieve this through their specific three-dimensional structures that provide an optimal environment for the reaction to take place.
In low temperature which factors favor a forward reaction?
In low temperatures, factors such as an exothermic reaction, a decrease in entropy, and the presence of a catalyst can favor a forward reaction. Lower temperatures decrease the kinetic energy of particles, allowing for better control over the reaction conditions towards the desired outcome.
Why is a low temperature not used in the haber process?
A low temperature is not used in the Haber process because the reaction between nitrogen and hydrogen to form ammonia is an exothermic reaction, meaning it releases heat. Using a higher temperature allows for a higher reaction rate, but temperatures that are too high can lead to decreased ammonia yield due to the reverse reaction occurring.
what refers to reactions that give off energy as they occur?
Such reactions are called Exothermic reactions. Their change in enthalpy is negative. Such reactions are favorable at low temperature.
What is the difference between Endothermic and Exothermic in five to ten points?
Endothermic and exothermic are both terms used for the transfer of heat through a chemical reaction. When the mixed chemicals give off more heat than before (Become hotter), than an exothermic reaction has occurred. This is where energy is given off to the surroundings, causing the temperature to rise. Exothermic reactions are the opposite to this, where the container holding the chemicals becomes colder. This is because energy was required and heat was taken from the surroundings for the reaction to occur. Hope this helps.
Why is synthesis of p-nitro acetanilide carried out at low temperature?
Synthesis of p-nitro acetanilide is carried out at low temperature to minimize side reactions and to control the rate of the nitration reaction. Low temperature helps to improve the selectivity of the reaction, favoring the desired product formation over potential byproducts.
Where is thinning of ozone most evident?
The thinning of ozone layer is most pronounced at the poles of the earth. It is because of the low temperature of the low temperature there. The ozone depleting reactions are carried on the polar stratospheric clouds i.e. the PSC's. these PCS's require minimum temperature for their formation which is possible only on the poles.
Why there is ozone gap on top of Antarctica specifically?
Ozone layer thinning is most pronounced over the Antractica because of a no of factors some of which are: 1) The CFC's released by humans are carried towards the Antarctica by the westerlies or the westerly winds where they cause ozone depletion. 2) the poles are the regions having low temperature and the ozone depleting reactions are only carried in temperature below -2o temperature that is on the polar stratospheric clouds. This attainment of temperature as low as 2o is only possible on the poles.
Does endothermic have a high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.
Why do sugars break down quickly in your body?
enzymes allow your body too initiate chemical reactions at low temperature and to control the rate of reactions.
What are chemical reactions that release energy in the abscence of oxygen called?
Anaerobic reactions, like fermentation or anaerobic respiration, occur in the absence of oxygen and release energy by breaking down glucose or other molecules into simpler compounds. These reactions are important for organisms that live in environments with low oxygen levels.
Why does a low temperature produce the maximum amount of ammonia?
A low temperature favors the exothermic direction of the ammonia synthesis reaction, leading to higher yields of ammonia. At low temperatures, the reaction rate is slower but more ammonia is produced as it shifts towards the product side due to Le Chatelier's principle.
Why can a low temperature cause death?
because all the reactions happening in your body (the things keeping you alive) are unable to work at a temperature under 37 degrees
Why is low body temperature desirable for animals in the winter?
Low body temperature during the winter slows down the need for nutrition. Most of the body's cellular reactions slow down as well. Many animals hibernate which puts their body temperature so low that they must sleep.
Explain some of the way that rainwater is carried to the people who need it?
the rain water has the temperature so low to help the people who need it
