For the reaction N2(g) + 3H2(g) ⇌ 2NH3(g) (exothermic), what happens to the yield of ammonia if temperature is increased?
A
Yield of NH3 decreases — equilibrium shifts left (favours endothermic reverse reaction)
B
Yield of NH3 increases — higher temperature increases reaction rate
C
Temperature has no effect on yield in the Haber process
D
All NH3 decomposes back to N2 and H2 at high temperature
