Consider the reaction: A (aq) ⇌ B (aq) at 253 K where the initial concentration of A = 1.00 M and the initial concentration of B
Ugo [173]

Answer:

The maximum amount of work that can be done by this system is -2.71 kJ/mol

Explanation:

Maximum amount of work denoted change in gibbs free energy (\Delta G) during the reaction.

Equilibrium concentration of B = 0.357 M

So equilibrium concentration of A = (1-0.357) M = 0.643 M

So equilibrium constant at 253 K, K_{eq}= \frac{[B]}{[A]}

[A] and [B] represent equilibrium concentrations

K_{eq}=\frac{0.357}{0.643}=0.555

When concentration of A = 0.867 M then B = (1-0.867) M = 0.133 M

So reaction quotient at this situation, Q=\frac{0.133}{0.867}=0.153

We know,  \Delta G=RTln(\frac{Q}{K_{eq}})

where R is gas constant and T is temperature in kelvin

Here R is 8.314 J/(mol.K), T is 253 K, Q is 0.153 and K_{eq} is 0.555

So, \Delta G=8.314\times 253\times ln(\frac{0.153}{0.555})mol/K

                           = -2710 J/mol

                            = -2.71 kJ/mol

PLEASE HELP ME IM CONFUSED
lisov135 [29]

Given -

T = 450K

∆H = 3000J

∆S = 4J/K

Using formula

∆G = ∆H - T∆S

∆G = 3000- 4*450

∆G = 1200 Joule

∆G is positive so the reaction is non spontaneous!
