Answer:
Only gives spontaneous reaction.
Explanation:
A redox reaction will be spontaneous if standard reduction potential () of the reaction is positive. Because it leads to negative standard gibbs free energy change (), which is a thermodynamic condition for spontaneity of a reaction.
Where and represents standard reduction potential of reduction half cell and standard reduction potential of oxidation half cell.
(1) Oxidation: ;
Reduction: ;
So,
Hence this pair will give spontaneous reaction.
(2) Similarly as above,
Hence this pair will give non-spontaneous reaction.
(3) Similarly as above,
Hence this pair will give non-spontaneous reaction.
(4) Similarly as above,
Hence this pair will give non-spontaneous reaction.
Answer:
it increases
Explanation:
when particles increase pressure increases
Physicist Ernest Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections.
Answer:
Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules. This break up is caused by coming into contact with the solvent. In the case of salt water, the water molecules break off salt molecules from the larger crystal lattice.
Explanation:
Answer:
- To increase the temperature as it is a reactant in terms of its endothermicity.
- To remove it will enable more space for the reactant to favor its production.
- To add more reactant in order to increase its equilibrium concentration.
Explanation:
Hello,
The undergoing chemical reaction is:
Thus, in order to intensify the amount of nitrogen as the chemical reaction is endothermic, considering the Le Chatelier's principle we state:
- To increase the temperature as it is a reactant in terms of its endothermicity.
- To remove it will enable more space for the reactant to favor its production.
- To add more reactant in order to increase its equilibrium concentration.
Best regards.
