Answer:
(A) The statement is false. The starting material is favored at equilibrium
Explanation:
As we know that type of reaction is predicted by value Gibbs free energy.
ΔG >0 It means that reaction is non spontaneous and favors the reactant of the reaction.
ΔG <0 It means that reaction is spontaneous and favors the product of the reaction.
As we know that
ΔG = ΔH -T ΔS
Here given that Assume the entropy term is small compared to the enthalpy term so ΔS = 0
⇒ ΔG = ΔH
Given that
ΔH o = 65 kJ/mol,
ΔG = ΔH = 65 kJ/mol
ΔG >0 It means that reaction is non spontaneous and favors the reactant of the reaction.
So the option A is correct.
(A) The statement is false. The starting material is favored at equilibrium.
Answer:
C
Explanation:
consider thermodynamics - heat is transferred from a warmer system to a cooler system. this is why m&ms melt in your hand when you hold them in your palm: your body heat is transferred the the m&ms, causing them to melt.
go back and review endothermic and exothermic reactions, that will help :)
Answer:
Explanation:
Evaporation is inhibited by high humidity. Low humidity is as result of hotter temperatures that is temperature when the cup of water is under the sun and vice versa for high humidity.
Relative humidity defined as the amount of water vapor in the surrounding air compared with the maximum possible. At its maximum which is termed saturation, relative humidity is 100% and evaporation is inhibited.
The amount of water vapor the air can hold depends on its temperature. Relative humidity rises at low temperatures for example in an air conditioned environment. As the air temperature declines, sometimes reaching the dew point relative humidity is 100%, and fog may result from the condensation of water droplets if they are small enough to stay in suspension.
Drying is more effective with hot air rather than cold air, because hot air can hold more water vapor. The capacity of air to hold water vapor is based on vapor pressure of water. The liquid and solid phases are continuously giving off vapor because some of the molecules have high enough speeds to enter the gas phase.
Therefore, a cup of water placed in the sun will have a reduced water level compared to that in an air conditioned room.
