Question

If the K H values for Ar ( g ) , CO 2 ( g ) , HCHO ( g ) and CH 4 ( g ) respectively are 40 . 39 , 1 . 67 , 1 . 83 × 10 - 5 and 0 . 413 , then identify the correct increasing order of their solubilities., HCHO CH 4 CO 2 Ar, HCHO CO 2 CH 4 Ar, Ar CO 2 HCHO CH 4, Ar CO 2 CH 4 HCHO

MARKS App · Accepted Answer

According to the Henry's law, the solubilities is inversely proportional to the hydration constant K H . So, higher the solubility, lower the K H value. So, the formaldehyde has the lowest K H value. So, it has the highest value of solubility. The order of solubility is Ar CO 2 CH 4 HCHO .
