Question

N2+ 3H2 gives 2NH3 ;∆H=-92.3 find the effect of temperature above equation

Answer 1

On increasing the temperature the reaction would go backwards.

And, on decreasing the temperature the reaction would proceed forward.

Hope it helps ❤️❤️

Answer 2

N2+3H2=2NH3;ΔH=92.3

   ΔH=ΔU+ΔnRT

OR

ΔU=ΔH-ΔnRT

Δn=2-4= -2

ΔU= -92.3 -(2RT)

      = -92.3 -(2*8.31*10^-3*298)

      = -92.3+4.955

ΔU=87.345 kjmol^-1
