what is the catalyst for the contact process?
V2O5 (heterogeneous)
1 of 5
give the equations for the two reactions involved in catalysing the contact process.
V2O5 + SO2 --> V2O4 +SO3 AND V2O4 + 0.5 O2 --> V2O5 (catalyst regenerated)
2 of 5
what is the reaction that occurs in catalytic converters?
2CO + 2NO => 2CO2 + N2 ( rhodium or platinum catalyst)
3 of 5
how does a homeogeneous catalyst work?
by forming an intermediate species, which then reacts with the products to reform the catalyst. the activation energies of these two reactions are lower than the activation energies of the uncatalysed reaction.catalyst is always reformed.
4 of 5
give the equations for the reaction between iodide ions and peroxodisulfate ions.
S208 2- + Fe 2+ => 2Fe 3+ + 2SO4 2- AND 2Fe 3+ + 2I- =>I2 + 2 Fe 2+
