Reactants must be moving fast enough and hit each other hard enough for a chemical reaction to take place. Increasing the temperature increases the average speed of the reactant molecules. As more ...

The reaction in which aluminum with water produces hydrogen: 2Al + 6H2O → Al2(OH) ... of hot NaCl at around 1000°F as a heat sink for pressurized distillation of seawater.

The aluminum–water reaction splits water without using electricity. Interest in making the reaction practical for the hydrogen economy first took off in the 1970s.
