The hydrogenation of unsaturated hydrocarbons is

an important industrial process. Precious metals,

such as platinum and palladium, can greatly

increase the rate of this reaction. During this

process, the gaseous reactants are pumped

across a layer of metal powder. An example of this

process is shown below.

Describe how the metal probably increases the

reaction rate, identify whether this is an example

of homogeneous or heterogeneous catalysis, and

explain how you know

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

i think that is the right

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

a chemical change results in a new substance being formed; whereas a physical change will result in a different state of matter
