Increasing temperature affects a reaction in two ways:
1) at higher temperatures the molecules are moving around faster and collisions and reactions are more frequent, so the reaction - both forward and reverse - speed up.
2) at higher temperatures, the equilibrium state will shift. In some cases it will shift the equilibrium towards the product. In other cases, it will shift it back towards the reactants.

How does temperature affect the Keq of a reaction?
Changing the temperature will change Keq. (apex.)
What happens to the temperature when the mass is increased in a chemical reaction involving magnesium and hydrochloric acid?
Increasing the mass of magnesium in a reaction with hydrochloric acid will not directly affect the temperature of the reaction. The temperature will be determined by the amount of heat released or absorbed during the reaction, which depends on the specific reaction and the initial conditions.
How do changes in temperature affect the rate of a reaction?
Increasing temperature generally increases the rate of a reaction because it provides more energy for the reactant molecules to overcome activation energy. Lowering the temperature can slow down the reaction as there is less energy available for the reactant molecules to collide effectively and form products. However, extreme temperatures can denature enzymes and disrupt the reaction process.
How does increasing temperature affect the shift of equilibrium in a chemical reaction?
Increasing temperature can shift the equilibrium of a chemical reaction by favoring the endothermic or exothermic direction, depending on the specific reaction. This shift occurs because higher temperatures provide more energy for reactant molecules to overcome activation energy barriers, leading to an increase in the rate of the forward or reverse reaction.
Which has higer rate of reaction the one with higher temperature or not?
The greater the temperature, the faster the rate of reaction. This is due to the fact that increasing temperature increases the activation energy, which is the amount of energy needed to get a reaction started.
How does heat affect the rate of the reaction?
Increasing the temperature the reaction rate increase.
How would increasing the temperature affect the rate of a reaction?
Doubles it
How does temperature concentration and acidity affect reaction rate?
Generally increasing the temperature and concentration the reaction rate is higher.
How does changing the temperature of solutions affect the rate of reactions?
In most cases, increasing the temperature increases the rate of the reaction.
Is it true when a reaction is at a equilibruim increasing the temperature favors the reaction that releases energy as heat?
No that is false. Increasing temperature favors the reaction that absorbs energy, not that releases energy as heat.
What are the three things that affect reaction rates?
The three main factors that affect reaction rates are the concentration of reactants, temperature, and the presence of a catalyst. Increasing the concentration of reactants or temperature generally speeds up reactions, while catalysts can increase reaction rates by providing an alternate reaction pathway with lower activation energy.
How does temperature affect the Keq of a reaction?
Changing the temperature will change Keq. (apex.)
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.

What speeds up reaction and slows down reaction?
Factors that can speed up a reaction include increasing temperature, adding a catalyst, or increasing the concentration of reactants. On the other hand, factors that can slow down a reaction include decreasing temperature, decreasing the concentration of reactants, or increasing the activation energy required for the reaction.
