Answer:
(a) -49.9 kJ/mol;
(b) To the right;
(c) 34.6 kJ/mol
Explanation:
(a) For this reaction, since it's at equilibrium and standard states, we know that we can apply the equation:
Substituting the given variables:
(b) Notice that this reaction is spontaneous, since . This means reaction spontaneously proceeds to the right side. Besides, K > 1, this means products dominate over reactants, so reaction proceeds to the right.
(c) Given the expression of the formation constant, we can use the same expression to calculate the reaction quotient at non-standard conditions:
Now, notice that . In this case, we have an excess of the products, this means reaction will shift to the let left to restore the equilibrium.
Calculate:
Answer:
It increases when the temperature increases.
Explanation:
- According to Arrhenius relation: k = Ae(-Ea/RT).
- The rate constant of the reaction and also the rate of the reaction increases exponentially with increasing the temperature of the reaction.
- As the temperature increases, the no. of molecules that can posses the critical energy (activation energy) to initiate the chemical reaction and pass the energy barrier increases.
Answers:
<h2>The symbiotic relationship that occurs between an orchid and a tree would be classified as commensalism. Most orchids are epiphytes, which mean that that they grow on other plants. This benefits the orchids because they can grow on top of the canopy, which prevents the orchids from being walked on or eaten by ground-dwelling organisms.</h2><h3 /><h3>I HOPE TO IT'S HELP YOU:)</h3>
Answer:
C. As speed increases, kinetic energy increase exponentially
Explanation:
As you can see on the graph, the further right we move on the x-axis, the higher the values on the y-axis. This means that as one value increases, the other value also increases. The only answer choice that says this is C.
Hope this helps :)
The answer is Na+ Cl- and F+. Hope this helps!!!
