How does temperature affect spontaneity? a. if triangleH and triangleS have opposite signs, the temperature will determine spontaneity.

b. if the temperature is high enough, any reaction will become spontaneous

c. temperature will affect spontaneity only if triangleH and triangleS are both positive

d. if triangleH and triangleS have the same sign, the temperature will determine spontaneity

PLEASE HELP TYSM!!!

The correct option is d.

d) If ΔH and ΔS have the same sign, the temperature will determine the spontaneity

Explanation:

Consider the table attached at the bottom which shows Spontaneity and the sign of Enthalpy and Entropy terms.

We can clearly see from the table how temperature effects the Spontaneity.

If the signs of ΔH and ΔS are opposite, the spontaneity doesn't depend on the temperature.

If the signs of ΔH and ΔS are same, then the temperature effects the Spontaneity. If both have negative signs, reaction is spontaneous at low temperature. If both have positive signs, reaction is spontaneous at high temperature.

lol idk man i guess u gotta ask bill nye the science guy

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
