Answer:
At 15.2°C. Kinetic energy of molecules highly depends on the temperature - the warmer it is, the faster the molecules will move, especially in fluids (gases and liquids). If we consider that the formula for average kinetic energy of molecules is:
Ek = 3/2*k*T where k is Boltzmanns constant and 3/2 is, well, 3/2, kinetic energy of molecules really only depends on the temperature.
Explanation:
down then up to add to the power of it.
In a hydrogenation reaction a catalyst is used to transform an alkene to alkane. Hydrogenation is a chemical reaction involve chemical reaction between molecular hydrogen and another compound or element in a presence of catalyst such as nickel, palladium or platinum. The reaction involve breaking of carbon-carbon double bond in alkene in presence of catalyst.
