Typically heat will speed up a chemical reaction because it causes the actual atoms to move quicker and collide with each other causing a chemical reaction. For example a redox reaction where a electron is passed between atoms.

∙ 15y agoHeat is a very commonly used catalyst that is used to speed up chemical reactions. When more temperature, or heat, is added to a chemical reaction, then the chemical reaction would occur much more quickly than had it just been left there to react on its own.

∙ 14y agoaccording to rate law, rate of reaction(R) is equal R= K [concentration of the first reactant in the rate-limiting step]m [concentration of the second reactant in rate-limiting step]n and so on where m and n represent the molecularity (order) of the reaction. k is known as the rate constant which is defined as k=A e-E/RT. A is the steric factor, -E is activation energy of the rate-limiting step, R is the universal gas constant (8.314 J / mole.k), and T is the temperature.

Exothermic reactions are favoured at low temperature and endothermic reactions at high temperature. Low temperature doesn't mean 0 K. A certain minimum temperature is necessary to have an appreciable reaction rate.

What effect dose temperature have on reaction rate?
It depends on the original temperature, but the rule of thumb is that near normal room temperature, raising the temperature by ten degrees will roughly double the reaction rate.
Does a frozen or regular tennis ball fall faster?
the only way they could fall at different rates is if one were smoother than the other. temperature has little effect on the weight of a solid object.
What is the effect of temperature change to the amount of heat content of the substance?
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
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.
What is the effect of lowering temperature on the rate of burning?
it is the same
Do most chemical reactions occur at rates that are independent of temperature?
No.
Which environmental changes can cause an increase in the rates of reactions in cells?
increased temperature
What are the main factors that effect reaction rates?
Affinity and temperature.
What are different factors that affect the rates of chemical reactions?
Some different factors that affect the rates of chemical reactions include whether or not a catalyst is present, the concentration of the reactants, temperature of the reactants, & pressure in the case of gas phase reactions.
Which graphs likely represents the effect of temperature on photosynthetic reactions?
B. W
What are the rates that effect the rate of dissolving?
The polarity of solute and solvent, the concentration, the temperature.
How does increasing the temperature effect a chemical reaction?
Raising the temperature makes chemical reactions faster.
What are four ways that a chemist can control the rates of chemical reactions?
By changing concentration, temperature; pressure and volume (in the case of gases).
What are four ways chemists can control the rates of chemical reactions?
Varying the following parameters:- temperature- pressure- concentraton- stirring
How does temperature effect diffusion rates?
Temperature and diffusion rates are usually linearly proportional. As temperature increases diffusion rate also increases and vice versa. In most cases, diffusion rate will reach 0 after saturation or the maximum possible temperature.
What are the three ways discussed in our lessons that chemists can control the rates of chemical reactions?
The reaction rate is dependet on temperature, pressure and reactants concentration.
Can shifts in equilibrium systems be explained by considering the effect of a disturbance on a separate rates of forward and reverse reactions?
Yes. This is based on LeChateliers principle
