what is a spontaneous reaction? a. one that occurs only some of the time b. one that reaches equilibrium quickly c. one that occurs without added energy d. one that produces large amounts of heat

Answer

Answer:

C. One that occurs without added energy

Brief Explanations:

A spontaneous reaction is defined as a reaction that proceeds on its own without the need for external energy input. Option A is incorrect because spontaneous reactions proceed without this limitation. Option B is wrong as reaction rate/equilibrium speed is unrelated to spontaneity. Option D is incorrect because some spontaneous reactions absorb heat (endothermic) rather than releasing it.
