The delta G for the dissociation is 87,865 joule/kg.
The process is non-spontaneous because the value of Gibbs free energy is positive.
<h3>What is dissociation?</h3>
The breaking up of a compound into a simpler form that can be recombined under other conditions.
Given,
H = 145 kJ
Delta S = 195 J/k
Determining the G using the following process:
G = H -TS
G = 87,865 Joules/K
Thus, the value of Delta G is 87,865 and the process is non-spontaneous.

Answer:
The time of heating
Explanation:
Let us analyse the experiment closely; the temperature of the liquid increases as the time of heating increases. This implies that the temperature of the liquid is dependent on the time of heating of the liquid. The longer the time of heating, the greater the increase in temperature until the boiling temperature is eventually attained.
Hence, the temperature of the liquid is the dependent variable, the time of heating is the independent variable when the heating rate is held constant.
Answer:
An <u>Orbital </u>is the probability distribution of an electron in an atom or molecule.
Explanation:
As we know atom consists of sub-particles commonly known as protons, neutrons and electrons. The outer space around the nucleus where the probability of finding electrons is maximum is known as orbital. As the electrons are not precisely ordered around the nucleus hence it is not easy to tell the exact position of an electron.
Hence, four quantum numbers are used to locate the position of electrons around the nucleus.
i) Principle Quantum Number:
This number explains the main energy level which tend to increase in energy as the distance of electrons from nucleus are increased. Principle Quantum Numbers are integer number ranging from one to infinity. Hence, increase in this quantum number results in increase of the size of orbital.
ii) Azimuthal Quantum Number:
This Quantum Number explains the direction of particular orbital in 3-dimensional space. Also it is responsible for the shape of an orbital.
iii) Magnetic Quantum Number:
This Quantum Number also tells the direction of orbital in 3D space with respect to x, y and z axis.
iv) Spin Quantum Number:
This Quantum Number tells about the spin direction of an electron about its axis which may be clockwise or anticlockwise.
