Answer:
Kp = 0.35 & Kc = 0.0075
Explanation:
PCl₅ ⇄ PCl₃ + Cl₂
Initial(atm) 0.5 0 0
At equilibrium 0.5 - p p p
- Total pressure at equilibrium = 0.78
- 0.5 - p + p + p = 0.78
- p = 0.28
So partial pressure of PCl₅ = 0.5 - 0.28 = 0.22 atm
Similarly PCl₃ = 0.28 atm & Cl₂ = 0.28 atm
According to law of mass action
- Kp =
![\frac{(Ppcl3)(Pcl2)}{(Ppcl5)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28Ppcl3%29%28Pcl2%29%7D%7B%28Ppcl5%29%7D)
- Kp =
![\frac{(0.28)(0.28)}{(0.22)}](https://tex.z-dn.net/?f=%5Cfrac%7B%280.28%29%280.28%29%7D%7B%280.22%29%7D)
- Kp = 0.35
We know Kp = Kc x (RT)Δng
Δng = change in gaseous moles
= product moles - reactant moles
= 2 - 1
= 1
R = universal gas constant = 0.0821 lit. atm. mol⁻¹. K⁻¹
So Kc = ![\frac{(0.35) }{(0.0821 )(523 K)}](https://tex.z-dn.net/?f=%5Cfrac%7B%280.35%29%20%7D%7B%280.0821%20%29%28523%20K%29%7D)
= 0.0081
Answer:
Ionic bond.
Explanation:
Group 7 elements like Bromine (Br) and group 2 elements like Magnesium,(Mg) involved loss and gain of electrons which is typical with Ionic bonding.
Answer:mol solute / L soln. M = 5.50 mol / .600 L. M = 9.16 molar
Caffeine is a methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling.<span>
