How does temperature affect the chemical reactions of certain substances?
IT ACCELATATES THE CHEMICAL REACTIONS
Why is endo favored over exo in certain chemical reactions or processes?
Endothermic reactions are favored over exothermic reactions in certain chemical processes because they absorb heat from the surroundings, which can help maintain a stable temperature and prevent overheating. This can be beneficial in reactions that require precise control of temperature or in processes where excess heat could be harmful.
Why it is useful to measure temperature?
One reason is because certain reactions require a precise temperature to occur. If the temperature is not achieved and maintained precisely then the reaction will stop.
Reactions in cells take place at about?
Reactions in cells typically take place at a temperature of around 37 degrees Celsius, which is the normal body temperature for most organisms. This temperature is optimal for the enzymes and proteins involved in cellular reactions to function efficiently.
Is it true that lowering the temperature slows down most chemical reactions?
most chemical reactions dealing with enzymes preform best in a certain small temperature range, so increased or decreased temperatures could result in the slowing down of reactions
Are chemical reactions always spontaneous when H is negative and S is negative?
No, when H and S are both negative, the reaction will only be spontaneous below a certain temperature
What are stages of photosynthesis?
Photosynthesis consists of two stages: a series of light-dependent reactions that are temperature independent and a series of temperature-dependent reactions that are light independent. The rate of the first series, called the light reaction, can be increased by increasing light intensity (within certain limits) but not by increasing temperature. In the second series, called the dark reaction, the rate can be increased by increasing temperature (within certain limits) but not by increasing light intensity.
How can le chatelier help in industrial processes to maximize the yield of operation?
By creating a certain tendencies of the reactions (changing temperature, pressure, concentartons, volumes) this were made more efficient.
When a person gets hypothermia the enzymes in their body become less active how does this change affect the body's chemical reaction?
most chemical reactions require a certain input of energy, meaning they need to be at a certain temperature. when the temperature is too low or too high, these chemical reactions cant take place.
What are the two stages in photosynthesis?
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
Which graphs likely represents the effect of temperature on photosynthetic reactions?
An exponential graph is likely to represent the effect of temperature on photosynthetic reactions, as the rate of photosynthesis typically increases with temperature up to a certain point before leveling off or decreasing due to enzyme denaturation. The initial increase is due to higher kinetic energy and enzyme activity, while the decrease is a result of enzyme inactivation.
Are there exceptions to the rule for chemical reactions?
Yes, there are exceptions to the general rules governing chemical reactions. For instance, certain reactions may not follow the expected stoichiometry due to side reactions or the formation of intermediates. Additionally, some reactions can occur under non-standard conditions, such as varying temperature and pressure, which can alter reaction pathways. Furthermore, specific catalysts can lead to unexpected reaction outcomes, deviating from typical behavior.
