Which is true about reaction rates? 1. High reaction rates occur only in spontaneous reactions.
2. Low reaction rates occur only in nonspontaneous reactions.
3. Reaction rates are not dependent on high or low activation energies.
4. Reaction rates are not related to spontaneity.
ANSWER 4

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.

Answerstrong acids and bases completely dissociate in water.this is how strong acids and bases are defined. they will ionize 100% in solution, making a non-reversible reaction
