Answer:

The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

For the reaction N2(g) + O2(g)2NO(g) H° = 181 kJ and S° = 24.9 J/K G° would be negative at temperatures (above, below) K. Enter

12345 [234]

ΔG deg will be negative above 7.27e+3 K.

Explanation:

The ΔG deg with the temperature can be found using the formula and the formula is given below
ΔG deg = ΔH deg - T ΔS deg
Given data, ΔH deg = 181kJ and ΔSdeg=24.9J/K
-T ΔS deg will be always negative and ΔG deg = ΔH deg will be positive and ΔG deg will be negative at relatively high temperatures and positive at relatively low temperatures
solving the equation and substitute ΔGdeg=0
ΔGdeg = ΔHdeg - T ΔSdeg
T= ΔHdeg/ΔSdeg
T=181 kJ / 2.49e-2 kJK-1
By simplification we get
T=7.27 × 10^3 K.
Therefore, Go will be negative above 7.27 × 10^3 K
Since ΔG deg = -RT lnK, when ΔGdeg < 0, K > 1 so the reaction will have K > 1 above 7.27 × 10^3 K.
