MCQ
Potassium acetate on Koble's electrolysis produces:
- AC2H4
- BCH4
- CC2H6
- DC3H8
Explanation:
RCOOK/Na on electrolysis yields R − R + CO2 + NaOH + H2.

$(a)$ The vapour pressure of water at $280 K$ is $14.2$ $mm Hg$
$(b)$ $R =0.082 L$ atm $K ^{-1} mol ^{-1}$

(image) $\xrightarrow[{KOH}]{{KMn{O_4}}}\,B\,\xrightarrow[{FeC{L_3}}]{{B{r_2}}}\,C\,\xrightarrow[{{H^ + }}]{{{C_2}{H_5}OH}}\,D$
$D$ would be
$(A)$ $\Delta S _{ x \rightarrow z}=\Delta S _{ x \rightarrow y}+\Delta S _{ y \rightarrow z}$
$(B)$ $w_{x \rightarrow z}=w_{x \rightarrow y}+w_{y \rightarrow z}$
$(C)$ $w_{x \rightarrow z \rightarrow z}=w_{x \rightarrow y}$
$(D)$ $\Delta S _{x \rightarrow y \rightarrow z}=\Delta S _{x \rightarrow y}$
