For a reaction system at equilibrium, LeChatelier's principle can be used to predict the "effect of a stress on the system".
<u>Option: C</u>
<u>Explanation:</u>
Le Chatelier's theory can be implemented to forecast a system's behavior due to variations in pressure, temperature, or concentration that will lead in predictable and contested variations in the system adjustments to establish a new state of equilibrium. This means that adding heat to a process would favor the endothermic path of a reaction, because this decreases the amount of heat generated in the system.
Here shift in equilibrium take place when volume increase, the total pressure decreases, which have potential to reverse the reaction, while on increasing pressure of system, the total volume decreases of the gaseous system, which can shift an equilibrium in the direction of the fewer molecules.
Answer:
1.6 × 10³ s
Explanation:
Let's consider the following generic reaction.
A → B
The rate law is:
![rate=k \times [A]^{m}](https://tex.z-dn.net/?f=rate%3Dk%20%5Ctimes%20%5BA%5D%5E%7Bm%7D)
where,
rate is the reaction rate
k is the rate constant
[A] is the molar concentration of the reactant A
m is the reaction order
When m = 1, we have a first-order reaction. We can calculate the half-life for this reaction using the following expression.
Answer: 11.5 grams
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution
where,
Morality = 0.612 M
n= moles of solute
= volume of solution in ml = 100 ml
Now put all the given values in the formula of molarity, we get
Therefore, the mass of copper (II)nitrate required is 11.5 grams
It's 10.
Mass = density x volume
M = 1g/ml(10ml) = 10g
