How can the rate of a reaction be increased?

(a) increasing the temperature

(b) having a lower concentration of reactants

(c) having less surface area

(d) decreasing the amount of reactants

I think the answer is A- increasing the temperature.

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
