What is Δn for the following equation in relating Kc to Kp?<br> 2 SO2(g) + O2(g) ⇌ 2 SO3(g)

swat32

Answer:

Δ N = -1

Explanation:

Step 1: Data given

2 SO2(g) + O2(g) ⇌ 2 SO3(g)

For 2 moles of SO2 we need 1 mol of O2 to produce 2 moles of SO3

Step 2: Calculate Δ

Δ N wNill be the sum of moles of products minus the sum of moles of reactants.

Number of moles of products = number of moles of SO3 = 2

Number of moles of reactants = number of moles of SO2 + number of moles of O2 = 2 + 1 = 3

Δ N = 2 - 3 = -1

When 2 moles of Na(s) react with H2O(l) to form NaOH(aq) and H2(g) according to the following equation, 369 kJ of energy are evo

enot [183]

Answer:

Exothermic

q = -8.03 kJ/g

Explanation:

<em>When 2 moles of Na(s) react with H₂O(l) to form NaOH(aq) and H₂(g) according to the following equation, 369 kJ of energy are evolved.</em>

The thermochemical equation is:

2 Na(s) + 2 H₂O(l) → 2 NaOH(aq) + H₂(g) ΔH = -369 kJ

Since the energy is evolved, the reaction is exothermic, which is why the enthalpy of the reaction (ΔH) is negative.

The heat released (q) per gram of Na(s) is (molar mass 22.98 g/mol):

$\frac{-369kJ}{2molNa} .\frac{1molNa}{22.98gNa} =-8.03kJ/g$
