What effect does raising the temperature have on the speed of reaction for the forward reaction and why?

In general, but not always, increasing the temperature will increase the rate of the forward reaction. This is because an increase in temperature increases the speed at which the molecules move, increasing the kinetic energy, and thus making it easier to reach the activation energy. Of course, this is true only for endothermic reactions. If the reaction is exothermic, then increasing the temperature will slow down the forward reaction.

How does increasing the temperature effect a chemical reaction?
Raising the temperature makes chemical reactions faster.
What effect does raising the temperature of a chemical reaction?
2SO2(g) + O2(g) 2SO3(g)-The reverse reaction is favored.
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
Explain what it means for a reaction to be endothermic and what would happen to the temperature recorded by a thermometer in an endothermic reaction?
An endothermic reaction absorbs heat energy from the system. In an endothermic reaction a thermometer measuring the reactants and products would register a decrease in temperature.
How is temperature affect the spontaneity of a reaction with positive H and S?
∆G = ∆H - T∆S and ∆G has to be negative for the reaction to be spontaneous. So, ultimately the effect of temperature will depend on the value of ∆H. If ∆H is negative, and ∆S is positive, then temperature won't matter, and reaction will be spontaneous. If ∆H is positive, and ∆S is positive, then a high temperature will favor spontaneity. If ∆H is negative and ∆S is negative, then a low temperature will favor spontaneity. So, the answer to your question is the higher the temperature the more likely the reaction will occur spontaneously.

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.
What is the effect of temperature on the rate of diastase reaction?
The effect of temperature on the rate of diastase reaction is that it acts as a catalyst. Higher temperatures will speed up the reaction.
What effect temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
Does temperature effect the rate of chemical reaction?
yes.
Does the temperature have any effect on the reaction of water with alka-seltzer?
Ultimately, the temperature has little effect of the reaction of water and Alka-Seltzer. However, warmer water will make the reaction occur and finish a bit faster.
What are the main factors that effect reaction rates?
Affinity and temperature.
Why does thermal energy effect a chemical reaction?
Generally the reaction rate is higher at high temperature.
How does heat effect the solubility of a solution?
Raising the temperature of the solvent will increase the solubility ofa solute.
What effect would raising the temperature have on the cell?
There are a number of things that could happen when the temperature of a cell rises. These cells could explode for example.
Does temperature have an effect on chemical reaction?
Yes, because the temperature can change the state of the elements being chemical;y tested so yes it does have and effect
