Which of the following reaction does not occur in solvay ammonia soda process ?

Option: 1

(NH_{4})_{2}CO_{3} + H_{2}O + CO_{2} \rightarrow 2 NH_{4}HCO_{3}


Option: 2

2 KHCO_{3} \overset{\Delta}\rightarrow K_{2}CO_{3} + H_{2}O + CO_{2}


Option: 3

2 NaHCO_{3} \overset{\Delta}\rightarrow Na_{2}CO_{3} + H_{2}O + CO_{2}


Option: 4

2 NH_{4}Cl + Ca(OH)_{2} \rightarrow 2NH_{3} + CaCl_{2} + H_{2}O

As we learnt ,

The reactions involved in Solvay's Process are:

NH_{3}+CO_{2}+H_{2}O\rightarrow NH_{4}HCO_{3} \\NH_{4}HCO_{3}+NaCl\overset{30^{\cdot c}}{\rightarrow}NaHCO_{3}\downarrow +NH_{4}Cl \\NaHCO_{3}\overset{250^{\cdot C}}{\rightarrow} Na_{2}CO_{3}+H_{2}O+CO_{2}\\ 2NH_{4}Cl+Ca (OH)_{2}\rightarrow CaCl_{2}+2H_{2}O+2NH_{3}

Decomposition of KHCO3 does not occur in solvay ammonia soda process .

Therefore, option(2) is correct.
