How titanium dioxide crystals on noxer block catalyse oxidation reaction that remove NOx from the atmosphere?
Titanium dioxide absorbs the radiation which is given off from the sun. This excites the electrons in titanium dioxide to a higher energy level. The high energy electron from titanium dioxide reacts with oxygen to produce a superdioxide ion on the surface of the titanium dioxide crystals; O2 +e- O2- Water also reacts with the oxide to produce a hydrogen, hydroxyl radical and an electron which is given back to the titanium dioxide; H2O + O2 H+ + OH + e- "The overall reaction is therefore; H2O + O2 H+ + O2- + OH" The hydroxyl radical formed can then oxidise nitrogen dioxide to nitrate ions because it is a very powerful oxidising agent; NO2 + OH H+ + NO3- More of the nitrogen gases can be rendered as the superoxide produced on the surface of titanium oxide can be used to convert nitrogen monoxide into nitrate ions; NO + O2- NO3- Titanium dioxide absorbs the radiation which is given off from the sun.

What is the colour of ferrous sulphate crystals?how does this colour change after heating?
Enzymes catalyse biochemical reaction by lowering the activation energy.
is to catalyse or increase the rate of reaction without any change in itself .
Oxidation is a reaction in which an atom, molecule or compound loses an electron. OIL = Oxidation Is Lost; RIG= Reduction Is Gain LEO = Lose Electron in Oxidation; GER = Gain Electron in Reduction (LEO the lion says GER) Hydrolysis is a reaction in which a molecule or compound is broken down, by the addition of a water molecule (it is NOT the breaking of a water molecule into oxygen and hydrogen - that… Read More
catalyse the reaction.
Rust is an oxidation reaction between iron and oxygen from the atmosphere. Because the reaction adds oxygen from the atmosphere to the iron of the nail, a rusty nail will weigh more than an non-rusty one. The primary reaction is: 4Fe + 3O2 --> 2Fe2O3
* To be an oxidation reaction electrons have to be lost. * Any reaction that results in electrons being lost can be described as an oxidation reaction.

Fuels burning is an oxidation reaction.
enzymes are involved i the course of reaction. they catalyse the substrates and help in the reaction
Actually, enzymes are typically used to catalyse a biological reaction, leading to a faster reaction rate, not slower.
Initially, an increase in temperature will increase the rate of reaction - and the enzyme should be able to catalyse the reaction faster. However, past a certain point, which is different for different enzymes, the shape of the enzyme will change. This is known as denaturing, and means the enzyme will not be able to catalyse the reaction efficiently (or at all).
In this reaction the oxidation states of involved atoms are changed.
An oxidation-reaction involve a transfer of electrons.
These are not mutually exclusive. A reaction can be oxidation and exothermic. Oxidation reactions involve a change in oxidation state (charge) which is interpreted as a loss of electrons. Exothermic reactions release heat energy.
ive also been wondering the answer for this question
yes it is a decomposition reaction which is an oxidation reduction reaction
Oxidation is an exergonic reaction.
A reaction witrh oxygen is called oxidation. Generally oxidation involve lose of electrons.
Combustion is an oxidation reaction - a reaction with oxygen.
Oxidation = loss of electrons Reduction = gain of electrons Oxidation-reduction: a reversible chemical reaction (one reaction is of oxidation and the another of reduction).
They lower the activation energy needed to kick off the reaction and hence make the reaction proceed faster.
Enzymes aren't used up or denatured after they catalyse a reaction.
A catalyse substrate is an extraordinary substrate that speed up the reaction in a enzyme.
it provides the H+ ions to catalyse the reaction
The reaction is called oxidation, and the forms of oxidation include combustion (burning).
a reversible chemical reaction in which one reaction is an oxidation and the reverse is a reduction
Rusting is an oxidation reaction.
a reduction and oxidation reaction
oxidation reaction + reduction reaction = redox reaction!
No! A substrate is a reagent in a chemical reaction. Catalyse is the verb form of catalyst; a catalyst is a chemical species that participates in lowering the energy barrier of a chemical reaction and allow a reaction to occur more rapidly. A catalyst is not consumed in a reaction and therefore only a small amount of catalyst is required in any reaction (if required at all), whereas a substrate must be present in the… Read More

relationship between oxidation and oxidising agent in a redox reaction
Oxidation and reduction are two types of chemical reactions that often work together.
An OXIDATION reaction
This is because when we balance a redox reaction, the stoichiometric coefficients are such that the total positive Oxidation number in the reaction and the Total negative Oxidation number corresponds to the net charge of the reaction.

Metal ions catalyse the reaction
An Oxidation Reaction. It may also be a redox reaction.
Yummy, Chemistry :) Redox reactions - Oxidation reaction This is a reaction in which atoms have undergone a change in their oxidation state.
oxidation reaction is a reaction in which the following pracedure takes place: ~ oxygen is added to a substance ~ hydrogen is removed from a substance ~ electrons are removed
Enzymes are biological catalysts which cause the rate of a reaction to increase (by providing an alternate reaction pathway with a lower activation enthalpy). They are very specific to the reaction they catalyse.
Dehydrogenation is a type of oxidation reaction which involves the removal of an hydrogen atom(H) from a molecule or compound. Oxidation reaction in chemistry is simply the removal of an electron from an atom, molecule or compound. A substance that is oxidised loses an electron. There are a lot of different reactions that are oxidation reactions, dehydrogenation is just one example of an oxidation reaction.
