PCl\(_5\)\((_g\)) → PCl\(_3\)\((_s\))  +  Cl\(_2\)\((_g\))

In the equation above, the reaction will be spontaneous if

C\(_2\)H\(_5\)OH   +  CH\(_3\)COOH  ⇌  CH\(_3\)COOC\(_2\)H\(_5\)  +  H\(_2\)O

The reaction above is

CH\(_3\) - CH\(_2\) - COOCH\(_2\) - CH\(_3\)

From the condensed structure above, the reactants are

The stainless steel alloy is used for making

The gas that ammoniacal solution of CuCl\(_2\) is used to absorb from producer or water gas is
