Answer:
b. Add NO gas
Explanation:
According with Le Chatelier´s principle, when a reactant is added the equilibrium is displaced to the product(s), to achieve the equilibrium again. Therefore, if NO is added in the reaction, it will be produced more of NO2(g).
Gravity and thrust work against eachother
Answer:
Explanation:
a ) All the electronic levels below n = 3 have same energy so there will not be any evolution of energy in electronic transition from n=3 to n=2 or to n= 1 .
b ) Ionisation energy of ground state = 15 x 10⁻¹⁹ J per electron
= 15 x 10⁻¹⁹ x 6.02 x 10²³ J / mol
= 90 x 10⁴ J/mol
= 900 kJ / mol
c ) the shortest wavelength (in nm) of radiation that could be absorbed without causing ionization will correspond to n = 4 to n = 6
= (11 - 2 ) x 10⁻¹⁹ J
= 9 X 10⁻¹⁹ J
= 9 X 10⁻¹⁹ J / 1.6 X 10⁻¹⁹
= 5.625 eV
= 1244 / 5.625 nm
= 221.155 nm
at equilibrium.
<h3>Explanation</h3>
Concentration for each of the species:
There was no Y to start with; its concentration could only have increased. Let the change in be .
Make a table.
Two moles of X will be produced and two moles of Z consumed for every one mole of Y produced. As a result, the <em>change</em> in will be and the <em>change</em> in will be .
.
Add the value in the C row to the I row:
.
What's the equation of for this reaction? Raise the concentration of each species to its coefficient. Products go to the numerator and reactants are on the denominator.
.
. As a result,
.
.
The degree of this polynomial is three. Plot the equation on a graph and look for any zeros. There's only one zero at . All three concentrations end up greater than zero.
Hence the equilibrium concentration of Y: .
