An increase in temperature will cause the rate of a chemical reaction to

increased temperture causes rate or reaction to increase.

How do you treat patients

Patients should be treated with humble and love like the way babies are treated.

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.

What causes pressure changes of reactants to affect the reaction rate

The frequency of collisions is changed.

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 happens in a Lewis acid-base reaction

An acid accepts an electron pair from a base.

What is true of an Arrhenius acid

An Arrhenius acid donates H+ ions. (apex).

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 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.

Which has the smallest rate constant k

chemical changes causing leaves to brown in the fall

According to the rate law how do concentrations affect rate

The rate increases as concentrations increase.

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

The concentrations of the reactants
