Answer: 438 K
Explanation:
According to Gibbs equation:
= Gibb's free energy change
= enthalpy change = 20.1 kJ/mol = 20100 J/mol
T = temperature
= entropy change = 45.9 J/Kmol
A reaction is at equilibrium when = Gibb's free energy change is zero and becomes spontaneous when = Gibb's free energy change is negative.
T=437.9K
Thus the temperature at which the reaction change from nonspontaneous to spontaneous in the forward direction is 438 K
Answer:
Temperature is the average kinetic energy of the molecules. Absolute zero is the temperature where molecular motion stops and is the lowest possible temperature. ... The relationship between Celsius and Kelvin temperature scales is given by K = °C + 273.15.5
so the answer is <u>B</u>

The surface area affects evaporation because the more area exposed to air allowing water to acquire more heat energy hope this helps :)
