Discuss the various reactions involved in the Solvay process

An element occupies group number 1 and period number 3. This element heated in the air gives compound A. With water, it gives compound B which is a strong base. The reaction of B with ammonia gives compound C, which is used as a reducing agent in organic chemistry. Identify the element A, B, and C.

What is entropy? Why is the entropy of a substance taken as zero at 0K? Calculate the ΔG for the reaction? N2(g) + 3H2(g) → 2NH3(g) at 298K The value of equilibrium constant (K) is 6.6 × 105, R = 8.314 JK-1mol-1.
