Refrigerant may be of four type such as R-22, R 410A, R- 290, R-417 A

The refrigerator R410A having standing pressure of about 260 psi whereas saction pressure of about 120 to 130 psi and discharge pressure of about 450 to 500 psi.

Refrigerant R-410 is a cooling machine consists of equipments and chillers for air conditioning purpose along with coolant gas. This refrigerant have high cooling capacity which consumes less power. The suction pressure is 118 psi and discharge pressure is 400 psi.

Initially, 0.65 mol of PCl5 is placed in a 1.0 L flask. At equilibrium, there is 0.15 mol of PCl3 in the flask. What is the equi

borishaifa [10]

Answer : The equilibrium concentration of $PCl_5$ is, 0.50 M

Explanation : Given,

Initial moles of $PCl_5$ = 0.65 mole

Volume of solution = 1.0 L

Moles of $PCl_3$ at equilibrium = 0.15 mole

The balanced equilibrium reaction will be,

$PCl_5\rightleftharpoons PCl_3+Cl_2$

Initial moles 0.65 0 0

At eqm. (0.65-x) x x

Moles of $PCl_3$ at equilibrium = x = 0.15 mole

Moles of $Cl_2$ at equilibrium = x = 0.15 mole

Moles of $PCl_5$ at equilibrium = (0.65-x) = (0.65-0.15) = 0.50 mole

Now we have to calculate the concentration of $PCl_3,Cl_2\text{ and }PCl_5$ at equilibrium.

Formula used : $Concentration=\frac{Moles}{Volume}$

$\text{Concentration of }PCl_3=\frac{\text{Moles of }PCl_3}{\text{Volume of solution}}=\frac{0.15mole}{1.0L}=0.15M$

$\text{Concentration of }Cl_2=\frac{\text{Moles of }Cl_2}{\text{Volume of solution}}=\frac{0.15mole}{1.0L}=0.15M$

$\text{Concentration of }PCl_5=\frac{\text{Moles of }PCl_5}{\text{Volume of solution}}=\frac{0.50mole}{1.0L}=0.50M$

Therefore, the equilibrium concentration of $PCl_5$ is, 0.50 M

Determine if the phrases below are true for catabolic pathways only, anabolic pathways only,or can apply to both pathways, by so

Ivan

Answer:

Catabolic pathways;

Pathway produces more ATP than it consumes

Supplies NADH for oxidative phosphorylation

Anabolic pathways only:

Consumes more ATP than it produces

Can require reducing agent

Both pathways;

At least one enzyme is regulated

All reactions are catabolized by enzymes

One or more reactions are endergonic without ATP

Explanation:

Catabolic pathways;

Complete oxidation of glucose and then produces more ATP. Oxidative phosphorylation is an example of catabolic pathway.

From the given following conversions are considered as catabolic pathways.

Pathway produces more ATP than it consumes

Supplies NADH for oxidative phosphorylation

Anabolic pathways:

Anabolic pathways produces new molecules and it requires energy in the form of ATP for the formation of new bonds.

From the given following conversions are considered as anabolic pathways.

Consumes more ATP than it produces

Can require reducing agent.

Both pathways;

Metabolic pathways are occuring in the cell only few enzymes are regulate these pathways.

At least one enzyme is regulated

All reactions are catabolized by enzymes

One or more reactions are endergonic without ATP
