Nickel
The spark is the activation energy. It is the catalyst of the chemical reaction.
a catalyst provides a different path for a reaction to occur To lower the activation energy of a reaction
Provided the catalyst is appropriate for the reaction, it will accelerate the reaction. In other words, the reaction will reach equilibrium between reactants and products faster than it would otherwise have done. The catalyst is unchanged, i.e. at the end of the reaction it is in the same chemical state that it was in at the start. In living systems, the catalysts are made by cells and are called enzymes.
this because the chemical reaction between Oxygen & Hydrogen obviously the Hydrogen bonds between Oxygen & Hydrogen.
There is no reaction between H2O2 and K2Cr2O7 because both are oxidants.
The spark is the activation energy. It is the catalyst of the chemical reaction.
The type of reaction that occurs between Hexene and Hydrogen is nothing when the unactivated catalyst is around 100 degrees. When it is between 200 and 300 degrees there is extensive reaction.
A catalyst speeds up a reaction and an inhibitor slows down a reaction
The Haber process is the reaction between nitrogen and hydrogen to produce ammonia. An Iron Catalyst is used. The reaction is reversible, so is quite complicated to maintain.

Catalyst: a substance which promote and help a chemical reaction. Inhibitor: a substance which greatly reduces the rate of a chemical reaction.
A chemical reaction occurs between sodium hydroxide and hydrogen chloride. Adding more sodium hydroxide to the reaction causes it to speed up. If you add more of a reactant, such as sodium hydroxide, can it be considered a catalyst? Why or why not?
No. That's hydrogenation. Combustion is the exothermic reaction between a one substance (usually an organic compound) and oxygen. Simply put combustion is fire.
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.

reaction betwen sodiumbisulphite and hydrogen peroxide
They are not reacting. But there is a reaction between hcl and ammonia.
