a gas container in a thick walled balloon. when the pressure changes from __kPa to 114kpa, the volume changes from 0.654L to 1.3
Hunter-Best [27]

<span>To solve this we assume that the gas is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At number of moles the value of PV/T is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:</span>

P1V1/T1 = P2V2/T2

P1 = P2V2T1/T2V1

P1 = (114)(1.32)(596)/(715)(.654)

P1 = 191.80 kPa

The equilibrium constant "k" is used to determine the concentration of every product in a reversible reaction until equilibrium is reached. At equilibrium, the value of k is equal to 1.

When the value of k is less than 1, this means that the concentration of the reactants is more than the concentration of the products. To reach equilibrium again, the reaction will shift to the left forming more products to compensate for the concentration.

Based on this, there are only two choices which are: 
<span>The concentration of one or more of the products is small.
</span><span>The reaction will not proceed very far to the right.

The other two are incorrect as:
The concentration of the reactants is more and not less
The reaction will generally form more products than reactants.</span>

What are some things in life that involve chemistry and how does chemistry apply?
Nady [450]
A lot of things in life involve chemistry. Let's start from the most obvious one - cooking.
While you are cooking, you need to mix ingredients and create homogeneous and heterogeneous mixtures, which is where chemistry is applied. Also, all of these ingredients change their physical and chemical state, which is also what chemistry studies.
