Answer: The reaction must proceed in the reverse direction.
Explanation:
is the constant of a certain reaction at equilibrium while is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
The expression of for above equation follows:
We are given:
There are 3 conditions:
When ; the reaction is product favored.
When ; the reaction is reactant favored.
When ; the reaction is in equilibrium.
As, , the reaction will be favoring reactant side or the reaction must proceed in the reverse direction.
Hence, the reaction must proceed in the reverse direction.
Answer:
Option (2)
Explanation:
The water in most of the region is generally pumped out of the ground for the purpose of irrigation. This rate of pumping is much higher than the rate of replenishment. The over-pumping of water leads to the lowering of the water table
About 60 to 70% of the water that is used for irrigation purposes does not reach the crop. It is because the water most of the time gets percolated down into the deeper zones. In addition to this, the water also leaks through the fractures that are associated with the canals and increasing rate of evaporation.
Thus, the correct answer is option (2).
Answer:b never reaches the crop hopefully helps
Explanation:
B) Weak electrolytes dissolve and partially dissociate in water providing charged ions to conduct electricity.
C) Weak electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.
D) Weak electrolytes dissolve and does not dissociate in water providing no charged ions to conduct electricity.
Answer: B) Weak electrolytes dissolve and partially dissociate in water providing charged ions to conduct electricity.
Explanation: Weak electrolytes are those substances which do not dissociate completely when dissolved in water. They dissociate but then associate back and thus their dissociation is shown by an equilibrium sign. Example:
The charged species formed helps in the conduction of electricity.
Strong electrolytes are those substances which dissociate completely when dissolved in water. Their dissociation is shown by a forward arrow. Example:
The charged species formed helps in the conduction of electricity.
Which substance has the lowest [H+] concentration but is still considered an acid?
Answer:
(A) - Milk
Explanation:
Acids cannot go below the 7 mark, and milk is the last one right before 7
Explain, in terms of collision theory, why increasing the pressure of the gases in the cylinder increases the rate of the forward reaction.
Determine the amount of heat released by the production of 1.0 mole of SO3(g).
State, in terms of the concentration of SO3(g) , what occurs when more O2(g) is added to the reaction at equilibrium.
Increasing the pressure will mean that these particles will collide more frequently to yield the products hence driving the forward reaction.
According to the collsion theory, reaction occurs as a result of collision between reactants in a system. Now we have the reaction; 2SO2(g) + O2(g) <==> 2SO3(g) + 392 kJ.
We can see that there are more particles on the left hand side than on the right hand side. Increasing the pressure will mean that these particles will collide more frequently to yield the products hence driving the forward reaction.
Now;
2 moles of SO3(g) produces 392 kJ of heat
1 mole of SO3(g) produces 1 mole * 392 kJ /2 moles
= 196 kJ
