A water bath in a physical chemistry lab is 1.85m long, 0.810m wide and 0.740m deep. If it is filled to within 2.57 in from the

jenyasd209 [6]

Answer:

The volume of water in water bath is 1,011 Liters.

Explanation:

Length of the water bath, L = 1.85 m

Width of the water bath, W= 0.810 m

Height of the water bath ,H= 0.740 m

Height of the water in water bath, h= 0.740 m - 2.57 inches

1 m = 39.37 inch

$= 0.740 m - \frac{2.57}{39.37} m = 0.6747 m$

Volume of the water in bath = L × W × h

$=1.85 m\times 0.810 m\times 0.6747 m=1.011 m^3$

$1 m^3=1000 L$

$1.011 m^3=1.011\times 1000 L=1,011 L$

The volume of water in water bath is 1,011 Liters.

Calculate the change in the standard entropy of the system, delta s degree for the synthesis of ammonia from N_2(g) and H_2(g) a

Svet_ta [14]

Answer:

$\Delta S^{0}$ for the reaction is -198.762 J/K

Explanation:

$N_{2}(g)+3H_{2}(g)\rightarrow 2NH_{3}(g)$

Standard change in entropy for the system ( $\Delta S^{0}$ ) is given by-

$\Delta S^{0}=[2moles\times S^{0}(NH_{3})_{g}]-[1mole\times S^{0}(N_{2})_{g}]-[3\times S^{0}(H_{2})_{g}]$

where $S^{0}$ represents standard entropy.

Here $S^{0}(NH_{3})_{g}=192.45J/(K.mol)$ , $S^{0}(N_{2})_{g}=191.61J/(K.mol)$ and $S^{0}(H_{2})_{g}=130.684J/(K.mol)$

So, $\Delta S^{0}=[2\times 192.45]-[1\times 191.61]-[3\times 130.684]J/K=-198.762J/K$
