Why can a catalyst speed up a reaction even at low temperature?
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
How does a catalyst speed a reaction at low temperature?
A catalyst reduces the amount of energy required to produce the reaction. This speeds up the reaction and causes it to finish more quickly. Raising the temperature will also speed up a reaction.
Why do catalyst allow the chemical reaction take place at 0 Celsius?
When reactants are joined by a catalyst, they no longer have to collide with much energy to react. Thus, with the catalyst present the reaction can proceed at very low temperatures.
How does a catalyst speed a reaction at low temperatures?
Catalysts will lower the activation energy needed for a certain reaction to happen. For example in the extraction of Aluminium from Bauxite (Aluminium Oxide) The melting point of Al2O3 is about 2000oC. But with the catalyst Cryolite (Na3AlF6), the overall melting point is lowered to about 950oC,
How does a catalyst speed up a reaction at low tempertures?
A catalysts speed up the rate of reaction by providing an alternate pathway which has a lower energy of activation than the normal pathway.

What is the best conditions for the haber process?
for maximum yield- low temperatures and high pressure, for maximum rate - high temperatures, high pressure and a catalyst.
What are things that decrease a reaction rate?
Some factors are: low temperature, low pressure, low concentration of reactants, no stirring, coarse particles, etc.
How do enzymes affect chemical reaction?
Usually enzymes have the role to catalyse a reaction. That means they aren't changed at all, but they influence the mechanism to reduce the activation energy (the energy needed for the reaction). The reaction is therefore performed more easily. To put it very simply: It speeds up a chemical reaction.
What is the catalyst used for hydrogenation of oils?
Due to fast reaction and increase D20 value or Hardness and low quantity of Hydrogen gas used catalysts are required for the reaction to be usable , as non catalytic hydrogenation takes place only at very high temperatures
High yield on the haber process?
Yield in the Haber process can be maximised by using low temperatures (as the synthesis of ammonia is endothermic) and high pressures (as it promotes the forward reaction as more moles of gas are on the reactants side). However, low temperatures mean a slow reaction rate so compromised temperatures of 300 degrees celsius must be used.
In the atmosphere sulfur trioxide will dissolve in rainwater to form dilute sulfuric acid This then falls to the earth as acid rain Is this process of forming dilute sulfuric acid product-favored?
Yes at low temperatures; no at high temperatures! If H° <0 and S° <0 then a reaction is product-favored at low temperatures but not at high temperatures.
Do catalyst work better in hot or cold water?
Most of us may familiar with hotter the better but it is not necessary that catalyst prefer hot temperature. Catalyst do provide alternative path with lower activation energy, and it is not necessary like heat if the trend of overall reaction is exothermic. Many catalyst work best on limited range of temperature not too high and not too low.
