if H and S have the same sign the temperature will determine spontaneity
Increasing the temperature makes a reaction spontaneous in some situations.
Increasing the temp makes reaction spontaneous in some situations -apex
(Explanation): sometimes, the spontaneity of a reaction depends on temperature, but in other cases, it is impossible for the reaction to be spontaneous, so temperature doesn't matter. It only matter in SOME situations.

A high temperature will make it spontaneous.
If H and S have the same sign, the temperature will determine spontaneity.
∆G = ∆H - T∆S and ∆G has to be negative for the reaction to be spontaneous. So, ultimately the effect of temperature will depend on the value of ∆H. If ∆H is negative, and ∆S is positive, then temperature won't matter, and reaction will be spontaneous. If ∆H is positive, and ∆S is positive, then a high temperature will favor spontaneity. If ∆H is negative and ∆S is negative, then a low temperature will favor spontaneity. So, the answer to your question is the higher the temperature the more likely the reaction will occur spontaneously.
S > 0 contributes to spontaneity.

S > 0 contributes to spontaneity.
∆G = ∆H - T∆S and for it to be spontaneous, ∆G should be negative. If both ∆H and ∆S are positive, in order to get a negative ∆H, the temperature needs to be elevated in order to make the ∆S term greater than the ∆H term. So, I guess the answer would be "the higher the temperature, the more likely will be the spontaneity of the reaction."
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
The speed of a given chemical reaction is directly responsible for spontaneity of the reaction. The reaction force and effect is contingent upon the speed of the reaction. The faster the reaction, the more force will be produced.
The Hotter the temperature, the faster the particle moves. During the reaction, atoms transfer in different molecules (or compounds), therefore the temperature does affect the speed of the reaction.

Generally increasing the temperature and concentration the reaction rate is higher.
Increasing the temperature the reaction rate increase.
