Question

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

Answer 1

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
