A catalyst is required when hydrogen reacts with iodine to help break the strong bond between hydrogen molecules, allowing them to react with iodine more readily. The catalyst assists in lowering the activation energy required for the reaction to occur, thereby increasing the rate of the reaction.

What is formed when water and iodine crystals and aluminium powder is combined?
When water, iodine crystals, and aluminum powder are combined, a reaction occurs in which hydrogen gas is evolved and a purple solution is formed due to the reaction of iodine with water. The aluminum powder reacts with water to produce aluminum hydroxide and hydrogen gas.
What is the results of carbon tetrachloride and iodine?
When carbon tetrachloride reacts with iodine in the presence of light, it forms an unstable compound called iodomethane and hydrogen iodide gas. This reaction is not commonly used due to the toxicity of carbon tetrachloride and the formation of harmful byproducts.
What is the function of KCLO3 in determination of carbon and hydrogen in sugar?
CAtalyst
What is the organic compound that reacts when iodine is added to starch solution?
The organic compound that reacts with iodine in a starch solution is amylose, which is a polysaccharide and a component of starch. When iodine is added to a starch solution, it forms a blue-black complex with the amylose present in the solution.
At what temperature does benzene react with chlorine without catalyst?
Benzene reacts with chlorine at room temperature without the need for a catalyst. This reaction occurs through a substitution reaction where one or more hydrogen atoms in benzene are replaced by chlorine atoms to form chlorobenzene.
What is formed when water and iodine crystals and aluminium powder is combined?
When water, iodine crystals, and aluminum powder are combined, a reaction occurs in which hydrogen gas is evolved and a purple solution is formed due to the reaction of iodine with water. The aluminum powder reacts with water to produce aluminum hydroxide and hydrogen 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.
What will the result of ethanol plus iodine be?
When ethanol reacts with iodine, it forms a yellow-brown solution due to the formation of iodoethane and hydrogen iodide. The reaction is a substitution reaction where iodine replaces a hydrogen atom in ethanol.
What does iodine typically bond with?
Iodine can mix with anything you, But it only reacts with a certain number of stuff. One reaction is: H2(g) + I2(g) --> 2HI(g) = Iodine and hydrogen mixed together Iodine also mixes with Fluorine, Bromine, It also reacts with to Chlorine, nitric acid, iodic acid.
Hydrogen gas reacts with iodine vapor equation?
The reaction between hydrogen gas and iodine vapor forms hydrogen iodide gas. The balanced chemical equation for this reaction is: H2(g) + I2(g) -> 2HI(g)
How many moles of hydrogen iodide are produced from 1 mole of iodine?
The balanced equation for the reaction between Iodine and Hydrogen is: H2 + I2 --> 2HI The ratio of I2 to HI is 1:2 Therefore 1 mole of Iodine can form a maximum of 2 moles of Hydrogen Iodide
What is the halogenation of 3-ethyl-1-pentene with iodine?
When Iodine solid reacts with this alkene in presence of ethanol 1,2-diiodo-3-ethyl penman is produced stereo chemistry of produced compound shows a significant role for determining the properties of product.
Is iodine highly reactive?
Iodine is not highly reactive under normal conditions. It is less reactive compared to other halogens like fluorine, chlorine, and bromine. It reacts with metals to form iodides or with hydrogen to form hydrogen iodide, but is relatively stable in its elemental form.
What is the name of the compound formed when lead reacts with iodine?
The compound formed when lead reacts with iodine is lead(II) iodide, with the chemical formula PbI2.
What are the reactants when nitrogen gas reacts with hydrogen gas to form ammonia?
The reactants are nitrogen gas (N2) and hydrogen gas (H2). They react together in the presence of a catalyst under high pressure and temperature to form ammonia (NH3).
When leadII nitrate reacts with sodium iodine what is the correct formua for the product leadII iodine?
Pbl2
When starch reacts with iodine what color appears?
purple
