Question

Show by either integrating the following form of the Euler equations, rho (u partial differential u/partial differential x + upsilon partial differential u/partial differential y) = - partial differential P/partial differential x and rho (u partial differential upsilon/partial differential m + upsilon partial differential upsilon/partial differential y) = - partial differential P/partial differential y, or by applying the Bernoulli equation for potential flows (neglect potential energy), that the pressure distribution in Problem 3 is P = - rho C_0^2/2 (x^2 + y^2) + C_2, where C_2 is an additive constant.

Explanation / Answer

Delta H of the reaction is positive , that is the reaction is endothermic. So favored only at high temperatures.

The condition of spontaneity is delta G = delta H - T x delta S should be negataive.

The temperature at which the reaction is at equilibrium is taken by considering Delta G= 0 at equilibrium.

Then DeltaH = T delta S

or T eq. = delta H / Delta S

= 467.9 x1000J /558.4 J

= 837.92

As the reaction is endothermic, above 838 K the reaction is spontaneous and below 838 non-spontaneous.
