For the reaction N2(g) + O2(g)→2 NO(g) H° = 181 kJ and S° = 24.9 J/K G°

The equilibrium constant, K, would be greater than 1 at temperatures (above or below).. Kelvin.

The equilibrium constant, K, would be greater than 1 at temperatures above 7269 Kelvin.

Explanation:-

Using Gibbs Helmholtz equation:

Where: T= Temperature =

= enthalpy change = 181 kJ/mol = 181000 J/mol  (1kJ=1000J)

= entropy change=  24.9 J/Kmol

The Gibbs free energy is related to equilibrium constant by following relation:

K > 1, when

Putting the values in the equation:

For < 0, >

Thus the equilibrium constant, K, would be greater than 1 at temperatures above 7269 Kelvin.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
