Calculate the equilibrium constant Kp for this reaction, given the following information (at 296 K ): 2NO(g)+Br2(g)⇌2NOBr(g)Kc=1.8 2NO(g)⇌N2(g)+O2(g)Kc=2.3×1030

Explanation:

The relation between Kp and Kc is given below:

Where,  

Kp is the pressure equilibrium constant

Kc is the molar equilibrium constant

R is gas constant

T is the temperature in Kelvins

Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)

For the first equilibrium reaction:

Given: Kc = 1.8

Temperature = 296 K

R = 0.082057 L atm.mol⁻¹K⁻¹

Δn = (2)-(2+1) = -1  

Thus, Kp is:

For the second equilibrium reaction:

Given: Kc =

Temperature = 296 K

R = 0.082057 L atm.mol⁻¹K⁻¹

Δn = (2)-(2) = 0

Thus, Kp is:

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
