On the issue of chemical balance and catalyst
The catalyst also changes the forward and reverse reaction rate.
If the chemical equilibrium does not move, then only the catalyst can change the time to reach equilibrium. If you change the temperature, pressure, it will affect the chemical balance.
Because the rate is scalar, it is not advisable to think too much from the speed change. I mean kv meaning that is proportional to the relationship, rather than proportional function relationship.
The catalyst can only improve the equilibrium speed, reducing the time to reach equilibrium, but will not affect the chemical balance.
