QAIPM-2011-Ch-1799: NEET 2011 Chemistry - Class 11 AIPM-2011-Ch-1799 Solution: A solution contains \(Fe^{2+} Fe^{3+}\) and \(I^-\) ions. This…

A solution contains

Fe^{2+} Fe^{3+}

and

I^-

ions. This solution was treated with iodine at

35^\circ C

E^\circ

for

Fe^{3+}/Fe^{2+}

is +0.77 V and

E^\circ

for

I_2/2I^- = 0.536\ \text{V}

. The favourable redox reaction is

I_2

will be reduced to

I^-

there will be no redox reaction

I^-

will be oxidised to

I_2

Fe^{2+}

will be oxidised to

Fe^{3+}

Multiple Choice Options

A Volume will become greater by a factor of 1.6.
B Volume will become greater by a factor of 1.1
C Volume will become smaller by a factor of 0.70
D Volume will become greater by a factor of 2.5

Step-by-Step Verified Solution

Given P 1 = 1.5 bar, T 1 = 273 + 15 = 288 K, V 1 = V P 2 = 1.0 bar, T 1 = 273 + 25 = 298K, V 2 = ? P 1 V 1 T 1 = P 2 V 2 T 2 _ 1.5 _ V 288 = 1 _ V 2 298 _ V 2 = 1.55V _ Volume of bubble will be almost 1.6 time to initial volume of bubble.
