Catalyst vs one without catalyst What is different

what is the purpose of catalyst in textile paint?

What part of the body is skin cancer most likely to affect

skin

What is relative rate constant

A relative rate constant the rate at which a reaction will take place.

Ex. V = k [A][B] the constant ,k, is a constant value for the rate of the reaction in said equation.

How do you treat patients

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

What must be known for the rate constant to be calculated from the rate law

The reaction rate at known reactant concentrations.

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 is true of an Arrhenius acid

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

What would happen to the rate of a reaction with rate law kNO2H2 if the concentration of NO were doubled

the rate would be four times larger. 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

Which has the largest rate constant k

Dynamite exploding

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

The concentrations of the reactants

How is the effect of concentration changes on the reaction seen in the rate law

Reaction rate increase when the concentration increase.

What is a rate law

An equation that relates the reaction to the concentrations of the reactants

What is the rate constant of a reaction if rate = 1.5(mol/L)/s, [A] is 1M, [B] is 3 M, m=2, and n=1

0.5

Apex
