As shown in table 15.2, kp for the equilibrium n21g2 + 3 h21g2 δ 2 nh31g2 is 4.51 * 10-5 at 450 °c. for each of the mixtures lis
Setler79 [48]
Our reaction balanced equation at equilibrium N2(g) + 3 H2(g) ↔ 2 NH3(g)
and we have the Kp value at equilibrium = 4.51 X 10^-5
A) 98 atm NH3, 45 atm N2, 55 atm H2

when Kp = [P(NH3)]^2 / [P(N2)] * [P(H2)]^3
                = 98^2 / (45 * 55^3) = 1.28 x 10^-3
by comparing the Kp by the Kp at equilibrium(the given value) So,
Kp > Kp equ So the mixture is not equilibrium,
 it will shift leftward (to decrease its value) towards the reactants to achieve equilibrium.
B) 57 atm NH3, 143 atm N2, no H2
∴ Kp = [P(NH3)]^2 / [P(N2)]
         = 57^2 / 143 = 22.7
∴Kp> Kp equ (the given value) 
∴it will shift leftward (to decrease its value) towards reactants to achieve equilibrium.

c) 13 atm NH3, 27 atm N2, 82 atm H2
∴Kp = [P(NH3)]^2 / [P(N2)] * [P(H2)]^3
       =  13^2 / (27* 82^3) = 1.14 X 10^-5
∴ Kp< Kp equ (the given value)
∴it will shift rightward (to increase its value) towards porducts to achieve equilibrium.

Answer:

  1. Option C) the chance of water-borne diseases.

Explanation:

When a <em>flood </em>happens, water will lpotentially get contaminated by several causes which include the overflow of untreated wastewater, the decomposition of the carcasses of animals and people, and the chemical contamination from industries.

In general, biochemical and chemical hazards are present in the water, after a flood, which means that the authorities and population should take extreme care for the use and intake of water: chemical treatment (use of chlorine), boil water. As usual, children and the elderly are the most at risk in those conditions.

Can the excess reactant (in stoichiometry) be negative?
strojnjashka [21]
No. Think about it this way: it’s a physical, leftover substance, you can never have a negative amount of anything.

If you’re speaking in terms of charge, however, then yes, it’s very likely.
