The reaction that proceeds in the forward direction is :
View answer and explanation
Correct option: B
NH4Cl+NaOH→H2O+NH3+NaCl\mathrm{N}{\mathrm{H}_4}\mathrm{Cl} + \mathrm{NaOH} \to {\mathrm{H}_2}\mathrm{O} + \mathrm{N}{\mathrm{H}_3} + \mathrm{NaCl}
Option B (NH4Cl+NaOH→H2O+NH3+NaCl\mathrm{N}{\mathrm{H}_4}\mathrm{Cl} + \mathrm{NaOH} \to {\mathrm{H}_2}\mathrm{O} + \mathrm{N}{\mathrm{H}_3} + \mathrm{NaCl}) is correct because it represents a strong base reacting with a weak acid salt to form a weaker base and a salt, which is a favorable reaction.

Given below are two statements: One is labelled as Assertion A and the other labelled as Reason R.
Assertion A: During the boiling of water having temporary hardness, Mg(HCO3)2Mg{(HC{O_3})_2} is converted to MgCO3MgC{O_3}.
Reason R The solubility product of Mg(OH)2Mg{(OH)_2} is greater than that of MgCO3MgC{O_3}.
In the light of the above statements, choose the most appropriate answer from the options given below
At a certain temperature, KPK_{\mathrm{P}} for the dissociation of solid CaCO3\mathrm{CaCO}_3 is 4.5×10−24.5 \times 10^{-2} atm and for the reaction C(s)+CO2(g)⇌2CO(g),\mathrm{C}(\mathrm{s})+\mathrm{CO}_2(\mathrm{g}) \rightleftharpoons 2 \mathrm{CO}(\mathrm{g}), the KPK_{\mathrm{P}} value is 2.0 atm.2.0 \mathrm{~atm}. The pressure of carbon monoxide at this temperature, when solid carbon CaO\mathrm{CaO} and CaCO3\mathrm{CaCO}_3 are mixed together and allowed to attain equilibrium is Phenolphthalein shows … in acid medium.
