This problem is asking to predict the pressure in the container at a temperature of 1,135 K with no apparent background; however, in similar problems we can be given a graph having the pressure on the y-axis and the temperature on the x-axis and a trendline such as on the attached file, which leads to a pressure of 21.2 atm by using the given equation and considering the following:
<h3>Graph analysis.</h3>
In chemistry, experiments can be studied, modelled and quantified by using graphs in which we have both a dependent and independent variable; the former on the y-axis and the latter on the x-axis.
In addition, when data is recorded and graphed, one can use different computational tools to obtain a trendline and thus, attempt to find either the dependent or independent value depending on the requirement.
In this case, since the provided trendline by the graph and the program it was put in is y = 0.017x+1.940, we understand y stands for pressure and x for temperature so that we can extrapolate this equation even beyond the plotted points, which is this case.
In such a way, we can plug in the given temperature to obtain the required pressure as shown below:
y = 0.017 ( 1,135 ) + 1.940
y = 21.2
Answer that is in atm according to the units on the y-axis:

Explanation:
electrons surrounds the necleus. Electrons have a negative charge. Protrons has positive
At anode,
Cd-----> + 2
At cathode,
+ 2e -----> Ni
Overall reaction,
+ Cd(s) ------> + Ni K=1.17
(aq) (aq) (s)
By nernst equation,
E= - Log K
Where,
F=96500c/mol
M=2
T=298K
E=Zero at equilibrium
R=8.314 J
0= - Log(1.17)
= 0.150v
what is nernst equation?
The Nernst equation is a chemical thermodynamical relationship used in electrochemistry that enables the determination of a reaction's reduction potential (half-cell or full-cell reaction) from the standard electrode potential, absolute temperature, the number of electrons involved in the oxydo-reduction reaction, and activities (often approximated by concentrations) of the chemical species undergoing reduction and oxidation, respectively. It was given the equation's original name in honor of the German physical scientist Walther Nernst.
The link between cell potential, standard potential, and the behaviors of electrically active (electroactive) species is described by the Nernst equation. It links the standard cell potential to the effective concentrations (activities) of the reaction's constituent parts.

Answer:
You would gain science knowledge, like if you wanted a science career this is more-than-likely something you would have to learn.
Emission and Absorbance of substances:
-Emission is the process where a substance gives off or emits radiation when it is heated or treated chemically. The level of emission of a substance depends on its spectroscopic composition and temperature.
-Absorption is the process where the electrons of a substance absorb or take up the energy wavelengths incident on them.
