Question

грлото. 1 Write mathematical equation of first law of thermodynamics for the following processes- a) Isothermal process b) Adiabatic process Write different oxidation states of Mn. Why Fe+3 is more stable than Fe+2.​

Answer 1

Answer:

In adiabatic process, there is no exchange of heat thus q=0. So First law becomes ΔU=W.

(b) Isochoric process, as it is carried in closed vessel ΔV=0 thus W=0. So first law becomes ΔU=q.
