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.
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.

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
