What does the rate law use to determine the rate of a reaction

The rate of a reaction is calculated using the concentrations of reactants.

Which of the following acts as a catalyst in catalytic converters

Metal

What does the pH of a solution depend on

The molarity. The hydrogen ion concentration.

If given the Ka just use the Henderson-Hasselbach equation

pH=pKa+log(base/acid)

Why does a reaction slow down with time

The reactant concentrations decrease

What information does the rate constant give from the rate law

It tells how much the reaction rate is affected by concentrations.

What is the rate constant of a reaction if rate 1 10-2 molLs A is 2 M B is 3 M m 2 and n 1

4.5 (moI/L)/s -apex

How does increasing temperature increase the number of reactions

It increases the collisions that have enough energy to react (apex)

What does a reaction energy diagram represent

A graph of Potential energy Vs time

The changes in energy during a reaction <APEX>

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 is the affect of concentration changes on the reaction rate seen in the rate law

?

What of the following is necessary to determine the rateof the reaction using the rate law

The concentrations of the reactants
