Aone-dimensional plane wall is exposed to convective and radiative conditions at x = 0. the ambient and surrounding temperatures are to 20°c and tsur 40°c, respectively. the convection heat transfer coefficient is h 20 w/m2 k, and the absorptivity of the exposed surface is a 0.78. determine the convective and radiative heat fluxes to the wall at x 0 if the wall surface temperature is t 24°c. assume the exposed wall surface is gray, and the surroundings are large.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
