Answer:
C. Keq will increase
Explanation:
Endothermic means the reaction will <em>absorb heat</em> to occur, hence an increase in temperature will favor the reaction, increasing the formation of products.
Keq is the equilibrium constant of the reaction, and it can be defined as:
In an endothermic reaction the equilibrium will be shift towards the formation of products when the temperature is increased, the concentration of products will increase (in relation to the concentration of reactants) ; so as a result the equilibrium constant Keq will also increase.
<u>Answer:</u> The spacing between the crystal planes is
<u>Explanation:</u>
To calculate the spacing between the crystal planes, we use the equation given by Bragg, which is:
where,
n = order of diffraction = 2
= wavelength of the light =
(Conversion factor:
)
d = spacing between the crystal planes = ?
= angle of diffraction = 22.20°
Putting values in above equation, we get:
Hence, the spacing between the crystal planes is
