Answer the correct answer out of the four is option c spectroscopy
Explanation- The interaction between electromagnetic radiation and matter studied. This study is commonly known as spectroscopy. It can also be named as study of absorption spectra or emission spectra.
The former spectrum is formed when energy is absorbed from Photons or light energy by electrons while the latter spectrum is formed due to a wavelength of light that is released when electrons jump from higher to lower level.
Answer:
0.24
Explanation:
We are given that
Rate constant for A=
Rate constant for B,k'=0.0750/s
We have to find the value of equilibrium constant for the reaction
Equilibrium constant, for k=
Using the formula
Hence, the value of the equilibrium constant for the reaction
at this temperature=0.24
Answer:
(A) proceeding without external influence once it has begun.
Explanation:
<em>A reaction that is spontaneous can be described as</em>
<em>(A) proceeding without external influence once it has begun.</em> TRUE. A spontaneous reaction has a tendency to proceed in the way it has begun. It is spontaneous when Gibbs free energy is negative.
<em>(B) releasing heat to the surroundings.</em> FALSE. If the reaction is exothermic (enthalpy negative), one still has to take into account the effect of the entropy on Gibbs free energy.
<em>(C) proceeding in both the forward and reverse directions.</em> FALSE. This just means that the reaction is reversible.
<em>(D) increasing in disorder.</em> FALSE. This means that entropy increases but it is still necessary to take into account the effect of enthalpy on Gibbs free energy.
<em>(E) having the same rate in both the forward and reverse directions.</em> FALSE. This is related to the kinetics but not the spontaneity.
Answer:
This relationship between pressure and volume is known as Boyle's lawA law that states that at constant temperature, the volume of a fixed amount of a gas is inversely proportional to its pressure., after its discoverer, and can be stated as follows: At constant temperature, the volume of a fixed amount of a gas is. The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. This can be easily understood by visualising the particles of gas in the container moving with a greater energy when the temperature is increased.
