The rate constants, K, can be expressed in many different terms. In this case, Kp is the equilibrium constant expressed in terms of gas partial pressure. The formula for this is:
Kp = [P(product C) × P(product D)] / [P(reactant A) × P(reactant B)]
As there is only one product, we will use only its pressure in the numerator.
Kp = [P(COCl2)] / [P(CO) × P(Cl2)]
P(COCl2) = 1.49 × 10⁸ × 2.22 × 10⁻⁴ × 2.22 × 10⁻⁴
P(COCl2) = 7.34 atm
Answer:
E
Explanation:
To solve this question, we need to know the oxidation number in the compound in the question. The name of the compound is tetraoxosulphate(vi) acid. We can obviously see that the oxidation number of sulphur in this particular compound is 6.
A. Is wrong
The name of the compound is trioxosulphate(iv) ion
B. Is wrong
S2O32-
2S + 3(-2) = -2
S = +2
C.is wrong
Oxidation state there is -2
D is wrong
The oxidation number here is zero
E is correct
Oxidation number of oxygen is -2 and that of chlorine is -1
Hence:
S + 2(-2) + 2(-1) = 0
S -4 -2 = 0
S = 4+2 = +6
D) O-O
The higher the difference in electronegativities of the two atoms, the more polar it is. Although oxygen is a very electronegative atom, it is bonded to itself which would make it a nonpolar bond.
It even and equally distributes the heat, therefore giving the food a more thorough cook in the microwave compared to one without a turntable.
The age of a material or how old the material is.
