Organic hydrogenation reactions, in which H2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. In the simplest case, ethene (C2H4) and H2 form ethane (C2H6). If 163 kJ is given off per mole of C2H4 reacting, how much heat is released when 16.0 kg of C2H6 forms?
A certain first order reaction has a rate constant of 0.0215 s-1 at 24 degrees C. What is the value of rate constant at 70 degrees C if Ea=90.0 kJ/mol.
A mixture of 82.49 g of aluminum ( Picture = 26.98 g/mol) and 117.65 g of oxygen ( Picture = 32.00 g/mol) is allowed to react. Identify the limiting reactant and determine the mass of the excess reactant present in the vessel when the reaction is ..
