Why is MnO2 added to the decomposition of H2O2 reaction?
MnO2 is added as a catalyst in the decomposition of hydrogen peroxide (H2O2) reaction to increase the rate of the reaction. It provides a surface for the reaction to occur on, which lowers the activation energy needed for the decomposition of hydrogen peroxide into water and oxygen gas.
Why is a catalyst not needed when benzene reacts with iodine chloride?
A catalyst is not needed in the reaction between benzene and iodine chloride because the reaction is spontaneous and occurs without requiring an external agent to speed up the reaction. The reaction proceeds due to the inherent reactivity of the reactants without the need for additional assistance from a catalyst.
When 0.1 mol of calcium reacts with 880 g of water 2.24 L of hydrogen gas form at STP How would the amount of hydrogen produced change if the volume of water was decreased to 440 mL?
The amount of hydrogen produced will not change since the production of hydrogen gas in the reaction is determined by the number of moles of calcium reacting, which remains constant at 0.1 mol. The volume of water does not affect the amount of hydrogen gas produced as long as the stoichiometry of the reaction is maintained.
What conditions are needed to produce ammonia?
The Haber process is used to produce ammonia under conditions of high pressure (150-200 atm) and high temperature (400-500°C) over an iron catalyst. It requires a careful balance of temperature, pressure, and catalyst to optimize ammonia production.
Will an increased temp and an increased concentration speed up a chemical reaction?
Generally, yes. Unless the product of the reaction should be ammonia for example, where a decreased temperature is needed. A catalyst from the transition metals will speed up a reaction too, for example a nickel catalyst in the process of the hydrogenation of margerine as it lowers the activation energy needed for the reaction to start. Increased pressure will also speed up the reaction, no matter what reaction is occurring.
What conditions are needed for hardening olive oil by reacting it with hydrogen?
the temperature needs to be 60c a nickel catalyst should be used to speed up the reaction
What is the role of a hydrogen peroxide decomposition catalyst in accelerating the breakdown of hydrogen peroxide into water and oxygen?
A hydrogen peroxide decomposition catalyst speeds up the reaction that breaks down hydrogen peroxide into water and oxygen. This catalyst lowers the activation energy needed for the reaction to occur, making it happen faster.
What role does a water electrolysis catalyst play in the process of splitting water into hydrogen and oxygen?
A water electrolysis catalyst helps to speed up the splitting of water into hydrogen and oxygen by lowering the energy needed for the reaction to occur. It acts as a facilitator, allowing the process to happen more efficiently and quickly.
What role does an electrolysis catalyst play in the process of converting water into hydrogen and oxygen?
An electrolysis catalyst helps to speed up the chemical reaction that breaks down water into hydrogen and oxygen during the electrolysis process. It lowers the energy input needed for the reaction to occur, making the process more efficient.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
Which chemical is needed to harden vegetable oil?
You need available hydrogen to saturate the c=c carbon double bonds. The presence of a catalyst will help move things along, something like nickel.
Does a catalyst decrease or increase the activation energy required?
The catalyst decrease the needed activation energy.
What is the activation energy needed for a chemical reaction decreased by?
The activation energy is decreased by a catalyst.
What role does a catalyst play in science?
A catalyst reduces the energy needed to start a chemical reaction.
What can reduce the amount of energy needed for a chemical reaction to take place?
adding a catalyst to the reaction
How do catalyst and inhibtors affect reaction rate?
A catalyst speeds up the reaction and lowers the amount of heat needed.
What is a catalyst install manager?
It is the install manager for the Catalyst software needed as a control panel for ATI/AMD graphics cards.
