Question

give a example of reaction where ∆H=∆u​

Answer 1

Answer:

For the reaction, 2HI(g)→H  

2

​  

(g)+I  

2

​  

(g), ΔH is equal to ΔU

ΔH =ΔU  +ΔnRT

For the reaction, 2HI(g)→H  

2

​  

(g)+I  

2

​  

(g), Δn =1+1−2=0

Hence, ΔH =ΔU  +(0)RT

ΔH =ΔU    

Note: Δn is the difference between the number of moles of gaseous products and the number of moles of gaseous reactants.
