What does lowering the temperature do to the rate of a reaction?
Decrease because particles will move slower causing less collisions.
What three things can alter the rate of an enzyme?
Three things that can alter the rate of an enzyme are; temperature, pH and substrate concentration. Enzymes will have an optimal temperature and pH, at which they will have the greatest rate. Below or above these optimum conditions, the rate will be slower.
Labs on temperature temperature affacting rate of photosynthesis?
Generally, it comes down to the basic laws of chemistry. As the temperature increases, particles become more 'excited' and move quicker, therefore increasing the rate of photosynthesis. The opposite happens when temperature decreased, the particles move slower and therefore decreasing the rate of photosynthesis.
How do temperature and pressure affect the rates of mass transfer in gassesliquids and solids?
the rate of mass thrnsfer can be affected higher in gases, slower in liquid and it is not affected in solid
The haber process is typically carried out at a temperature of 500 Celsius so what would happen if 100 Celsius?
It would happen at a much, much slower rate.
How does temperature effect frog heart rate?
the cooler the frog the slower the heart rate, the warmer the faster
What does lowering the temperature do to the rate of a reaction?
Decrease because particles will move slower causing less collisions.
Do the temperature affect the rate of evaporation?
Yes the hotter the weather the faster the evaporation, the colder the slower
Why does the frog heart have lower heart rate than mammalian heart?
Frog's internal body temperature is lower than that of a mammal lower temperature = slower heart rate

What is the rate of amylase activity at 25 degrees Celsius?
the rate would be slower because some enzymes are resistant to temperature change (denaturation)
Why does frozen liver react with hydrogen peroxide more than raw liver?
the frozen liver reaction should have been slower than the liver at room temperature, as this is the optimal condition for the enzyme catalase. The reaction would occur at a slower rate when an enzyme is below its optimal condition so generally when an enzyme is in cold conditions it will function slower.
Relationship between temperature and daphnia heart rate?
The higher the temperature, the faster the heart rate of the Daphnia. The lower the temperature, slower the heart rate of the Daphnia.

Does water evaporate without boiling?
Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation.
Does water evaporate faster at different temperatures?
Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation.
Why did ice water react slower than hot water to chalk and vinegar?
Generally the rate of reaction is improved at high temperature.
