A flat wall $($see figure B$)$ has heat generated in the wall

$($internal heat generation$)$ of qO $(=$W$/$h$.$m$3).$ The heat is

distributed only along the $x$ direction. The wall is

insulated. If the wall temperature on the outer surface of

the wall is constant at TW $(K)$ at $x=L$ and $x=-L$ and the

temperature in the middle of the wall is a maximum of

TO$.$ Arrange the temperature distribution equation so that

$T=f(x),$ if the thermal conductivity of the material is k $($W$/$

m$.$K$).$ State the assumptions you use!
