Answer:
A. for K>>1 you can say that the reaction is nearly irreversible so the forward direction is favored. (Products formation)
B. When the temperature rises the equilibrium is going to change but to know how is going to change you have to take into account the kind of reaction. For endothermic reactions (the reverse reaction is favored) and for exothermic reactions (the forward reaction is favored)
Explanation:
A. The equilibrium constant K is defined as
In any case
aA +Bb equilibrium Cd +dD
where K is:
![K= \frac{[C]^{c}[D]^{d}}{[A]^{a}[B]^{b}}](https://tex.z-dn.net/?f=K%3D%20%5Cfrac%7B%5BC%5D%5E%7Bc%7D%5BD%5D%5E%7Bd%7D%7D%7B%5BA%5D%5E%7Ba%7D%5BB%5D%5E%7Bb%7D%7D)
[] is molar concentration.
If K>>> 1 it means that the molar concentration of products is a lot bigger that the molar concentration of reagents, so the forward reaction is favored.
B. The relation between K and temperature is given by the Van't Hoff equation
Where: H is reaction enthalpy, R is the gas constant and T temperature.
Clearing the equation for 
we get:
Here we can study two cases: when delta 
is positive (exothermic reactions) and when is negative (endothermic reactions)
For exothermic reactions when we increase the temperature the denominator in the equation would have a negative exponent so is greater that 
and the forward reaction is favored.
When we have an endothermic reaction we will have a positive exponent so will be less than the forward reactions is not favored.
A solution is a homogeneous mixture, meaning it contains 2 or more substances. A solute is a substance that’s dissolved in the solvent. Think of it as dissolving salt (solute) in water (solvent) to make a salt solution. The amount of each substance in the solution impacts the concentration of it. So if I put more salt than water, it increases its concentration, while adding more water decreases its concentration.
My guess is chlorine since their right next to each other and i dont think their is a right answer due to the question saying predict
Answer:
X axis shows the independent and Y axis shows the dependent.
Explanation:
- As the independent variable is always plotted on the X-axis of the graph the Y-axis shows the dependent variable that is affected by the X variables Time is an independent variable and is always shown along the X-axis.
- Such as the image showed tells about the data of N2O biofuel emissions from 2009-10. Thus this will be plotted along the X-axis and Y-axis will show the amount of nitrogen fertilizer applied.
The temperature if the volume were changed to 225 ml at a pressure of 785 torrs is 129K.
Pressure is constant.
so
V1 / T1 = v2 / T2
so
T2 = V2 T1 / V1
T2 = 225 x 242 / 422
T2 = 129K
What is temperature?
Temperature is a measure of hotness or coldness expressed on several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which thermal energy spontaneously flows - ie, from a hotter body (one at a higher temperature) to a colder body (another at a lower temperature).
The Fahrenheit temperature scale (°F) is used in the United States and some other English-speaking countries. The Celsius temperature scale (°C) is standard in almost all countries that have adopted the metric system and is widely used in science. The Kelvin (K) scale, the absolute temperature scale is recognized as the international standard for scientific temperature measurement.
