The given sentence is part of a longer question.
I found this question with the same sentence. So, I will help you using this question:
For the reaction N2O4<span>(g) ⇄ 2NO</span>2(g), a reaction mixture at a certain temperature initially contains both N2O4 and NO2 in their standard states (meaning they are gases with a pressure of 1 atm<span>). If </span>Kp = 0.15, which statement is true of the reaction mixture before
any reaction occurs?
(a) Q = K<span>; The reaction </span>is at equilibrium.
(b) Q < K<span>;
The reaction </span>will proceed to
the right.
(c) Q > K<span>; The reaction </span>will proceed to the left.
The answer is the option (c) Q > K<span>; The reaction will proceed to the </span>left,
since Qp<span> = </span>1<span>, and 1 > 0.15.</span>
Explanation:
Kp is the equilibrium constant in term of the partial pressures of the gases.
Q is the reaction quotient. It is a measure of the progress of a chemical reaction.
The reaction quotient has the same form of the equilibrium constant but using the concentrations or partial pressures at any moment.
At equilibrium both Kp and Q are equal. Q = Kp
If Q < Kp then the reaction will go to the right (forward reaction) trying to reach the equilibrium,
If Q > Kp then the reaction will go to the left (reverse reaction) trying to reach the equilibrium.
Here, the state is that both pressures are 1 atm, so Q = (1)^2 / 1 = 1.
Since, Q = 1 and Kp = 0.15, Q > Kp and the reaction will proceed to the left.
A chemical change alters the chemical makeup of a substance. So, wood burning would be a chemical change. The others just alter the physical makeup of the substance.
<u>Answer:</u> The given reaction is non-spontaneous in nature.
<u>Explanation:</u>
To calculate the 
concentration, we use the equation:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
We are given:
pH of the solution = 7.5
![7.5=-\log [H^+]](https://tex.z-dn.net/?f=7.5%3D-%5Clog%20%5BH%5E%2B%5D)
![[H^+]=10^{-7.5)=3.1\times 10^{-8}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-7.5%29%3D3.1%5Ctimes%2010%5E%7B-8%7DM)
For the given chemical equation:
The equation used to Gibbs free energy of the reaction follows:
where,
= free energy of the reaction
= standard Gibbs free energy = 6.3 kJ/mol = 6300 J/mol (Conversion factor: 1kJ = 1000J)
R = Gas constant = 8.314J/K mol
T = Temperature = ![25^oC=[273+25]K=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B273%2B25%5DK%3D298K)
= Ratio of concentration of products and reactants = ![\frac{[BPG][NaDH][H^+]}{[G_3P][NAD^+][HPO_4^{2-}]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BBPG%5D%5BNaDH%5D%5BH%5E%2B%5D%7D%7B%5BG_3P%5D%5BNAD%5E%2B%5D%5BHPO_4%5E%7B2-%7D%5D%7D)
![[BPG]=3.0\times 10^{-3}M](https://tex.z-dn.net/?f=%5BBPG%5D%3D3.0%5Ctimes%2010%5E%7B-3%7DM)
![[NADH]=1.0\times 10^{-4}M](https://tex.z-dn.net/?f=%5BNADH%5D%3D1.0%5Ctimes%2010%5E%7B-4%7DM)
![[H^+]=3.1\times 10^{-8}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D3.1%5Ctimes%2010%5E%7B-8%7DM)
![[G_3P]=1.5\times 10^{-5}M](https://tex.z-dn.net/?f=%5BG_3P%5D%3D1.5%5Ctimes%2010%5E%7B-5%7DM)
![[NAD^+]=1.2\times 10^{-5}M](https://tex.z-dn.net/?f=%5BNAD%5E%2B%5D%3D1.2%5Ctimes%2010%5E%7B-5%7DM)
![[HPO_4^{2-}]=1.2\times 10^{-5}M](https://tex.z-dn.net/?f=%5BHPO_4%5E%7B2-%7D%5D%3D1.2%5Ctimes%2010%5E%7B-5%7DM)
Putting values in above equation, we get:
For the reaction to be spontaneous, the Gibbs free energy of the reaction must come out to be negative.
As, the Gibbs free energy of the reaction is positive. The reaction is said to be non-spontaneous.
Hence, the given reaction is non-spontaneous in nature.
Answer:
Endangered species and habitats simply mean that these species and habitats are about to extinct if not take important steps to save them. Many of us support this that we should take steps to save such species to maintain the ecosystem. On the other hand, there are many supporters of economic development even if in this habitat such as water bodies, forests, and other habitats are affected. If a habitat is affected or shrink in the development the species found in these habitats also affected and some might become endangered.
Losing the species and habitats will affect the ecosystem and biodiversity. It leads to disturbing in the health of the environment which affects the health and lifestyle of humans too. To maintain the health of the environment we need to prevent species to extinct and habitats to destroyed. Biodiversity and human should be in harmony and did not destroyed if we will not exploit there will be a better future.
