when the cations Na+ K+ Cs+ are combined with chloride ion in the gas phase to form ion pairs, which pair formation releases the greatest amount of energy? KCL or RbCl, or NaCl or CsCl.
The linear form (y=mx+b) of the Arrhenius equation is given below : ln K = -Ea/RT + Ln A 1) In order to find the activation energy (Ea) you will need to make a linear graph
Metallic aluminum reacts with MnO_2 at elevated temperatures to form manganese metal and aluminum oxide. A mixture of the two reactants is 67.2% mole percent Al.
Note that in some cases, the "product" may be the result of a proton transfer reaction. Do not assume that an aqueous workup (H3O+) is performed unless it is specified
