10) Draw the energy diagram for the reaction H2+ I2<--> 2HI where the activation energy for the forward reaction is 38.9 KJ and the enthalpy change is +3.6 K).

H tricky one let me think and get back to u

Pics pls i cant see without pics

The internal energy of the system we can term it as total potential energy and kinetic energy. energy flows out of the surrounding from the system then we can say that the internal energy of the final state is lower than its initials. the sign of  δesystem is negative.δesystem = efinal - einitial=-ve  efinal  ∠einitial.

What is your question i dont understand well sorry
