What would cause the greatest decrease in the rate of chemical reaction?
For most reactions, the lowering of the temperature of the reactants.
The Haber process is typically carried out at a temperature of approximately 500rm circ C What would happen to the rate of the forward reaction if the temperature were lowered to 100rm circ C?
Lowering the temperature to 100°C would decrease the rate of the forward reaction in the Haber process. This is because lower temperatures slow down the kinetic energy of the particles, resulting in fewer collisions between molecules, which in turn reduces the rate of reaction.
What effect temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
What increases the rate of a reaction by lowering the activation energy?
A catalyst can increase the rate of a reaction by lowering the activation energy needed for the reaction to occur. Catalysts provide an alternative reaction pathway with a lower activation energy, allowing the reaction to happen more quickly.
What happens If you decrease rate of chemical reaction?
Decreasing the rate of a chemical reaction would slow down the speed at which reactants are converted into products. This can be done by lowering temperature, decreasing reactant concentration, or adding inhibitors. Ultimately, the reaction will take longer to reach completion.

What effects the rate constant of a reaction?

Why does photographic film stay fresh longer if its kept in a refrigerator?
Lowering the temperature lowers the rate of the chemical reaction in the film. (NovaNet)
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.

What can alter the activation energy if a reaction?
A catalyst alter rate of reaction by lowering the activation

Is temperature essential in determining the reaction rate?
yes, as the reaction rate increases with increase in the temperature
