Predict the net reaction direction
a) if RXN heated at constant V
b) some N2F4 removed at constant T&V
c) Decrease P
d) catalyst is added
N2F4 (g) ⇄ 2 NF2 (g) >> ∆H= 38.5 kJ/mol

a) ∆H>0 >>endothermic reaction ,T increase, K decreases, a net change occurs in the direction is from left to right toward product

b) Conc. of the reactant decrease the system shift to left
( some NF2 combines to produce N2F4 )

c) P decrease the system shift to left .

d) if catalyst is added to reaction mixture ,the reaction will reach equilibrium faster but no change in the change equilibrium constant or shift equilibrium

ليش التفاعل من اليمين الى اليسار مع انو عدد المولات في النواتج اكثر من المواد المتفاعلة ؟
المثال كله مو فاهمته ممكن احد يشرح لي اياه :(
ولكم مني جزيل الششكر
