What is the effect of adding more water to the following equilibrium reaction

Equilibrium is pushed to the reactant side

Is 1pH more acid than 4pH

Yes, 1pH is more acid than 4pH

What causes the reaction rate to decrease as the reaction progresses

The concentration of the reactants decreases.

What happens to the potential energy of the molecules in a reaction

The potential energy of the molecules change during a reaction.

What does Le Chtelier's principle state

The Le Chtelier's principle states one thing. It is the dynamic equilibrium which is disturbed by changing the conditions and the position of equilibrium moves that makes a change.

What would happen if the equilibrium of a weak acid dissociation reaction were upset

The reaction would shift to balance the change

What is true of a Brnsted Lowry base

Bornsted Lowry base is an acid base reaction theory. The ideal came from Johannes Nicolaus Bronsted and Thomas Martin Lowry in 1923. The theory is that acid can lose or donate a proton.

How do you spell dielema

The correct spelling is "dilemma" (a predicament, a choice between two bad alternatives).

Which of the following best describes a bronsted lowry acid base reaction

Acid + Base = Salt+Water (APEX)

What equation would calculate the rate constant from initial concentration

The formula is:
k(T) = ([A][B])/r where:

- [A] and [B] are the concentrations of reactants
- r is the reaction rate

What of the following is a characteristic of a weak acid

It does not dissociate completely in water
