2SO2 + O2 ↔ 2SO3 : ΔΗ = - 197 kJ mol-1
Which of the following will NOT shift the equilibrium position to the right?
Adding more O2
Adding a catalyst
increasing the pressure
Lowering the temperature
If a (dynamic) equilibrium is disturbed by changing the conditions, the position of equilibrium................
Identify the incorrect statement about achieving equilibrium.
achieved when product and reactant concentrations are equal
achieved when forward and reverse reaction rates are same
achieved when concentration of reactants is stable/constant
achieved when concentration ratio of reactants to products becomes stable, thus fixing the equilibrium constant (equilibrium position)
For the reaction...

increase
decrease
remain the same
double
SO2 + O2 ↔ SO3
