Answer:
a) ΔGº= -49,9 KJ/mol = - 50 KJ/mol
b) The reaction goes to the right to formation of products
c) ΔG= 84,42 KJ/mol. The direction is to reactive, to the left
Explanation:
a) ΔGº= - RTLnKf
You need to convert Cº to K. 25ºC=298K
Then, ΔGº= - 3,814 J/molK * 298K* Ln(5.6 *10^8)= - 49906 J/mol = -49,9 KJ/mol = - 50 KJ/mol
b) The ΔGº < 0, that means the direct reaction is spontaneous when te reactive and products are in standard state. In other words the reaction goes to the right, to formation of products
c) The general ecuation for chemical reaction is aA + bB → cD + dD. Thus
ΔG=ΔGº + RTLn (([C]^c*[D]^d)/[A]^a*[B]^b)
In this case,
ΔG=ΔGº + RTLn ([Ni(NH3)62+] / [Ni2+]*[NH3]^6 )= 84417 J/mol =84,42 KJ/mol
ΔG >0 means the reaction isn't spontaneous in the direction of the products. Therefore the direction is to reactive, to the left
Answer:
Explanation:
There are three definitions of acids: Arrhenius, Bronsted - Lowry, and Lewis.
An Arrhenius acid is a substance that when dissolved in water will release a proton (H⁺ or hdyronoum, H₃O⁺) in solution.
The definition of Bronsted-Lowry is not limited to aqueous solution: an acid is a substance that releases protons in any solvent. So it includes, the Arrhenius acids but also other acids.
The Lewis Acid definition is wider. It includes both Arrhenius and Bronsted-Lowry acids and other substances that do not release protons. A Lewis acid is a substance that accepts an electron pair.
Thus, <em>when an acid is dissolved in a solution, following Bronsted-Lowry definition, </em><u><em>H⁺ ions are formed.</em></u>
Incomplete combustion<span> occurs when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide</span>
