Solution: Calculate Kp for each of the following reactions. Express your answer using two significant figures. a. N2O4(g) ⇌ 2NO2(g)                     K  c = 5.9 × 10−3 (at 298 K) b. N2(g) + 3H2(g) ⇌ 2NH3(g)            K c = 3.7 × 108 (at 298 K) c. N2(g) + O2(g) ⇌ 2NO (g)               K  c = 4.10 × 10−31 (at 298 K)

Problem

Calculate Kp for each of the following reactions. Express your answer using two significant figures.

a. N2O4(g) ⇌ 2NO2(g)                     K  c = 5.9 × 10−3 (at 298 K)

b. N2(g) + 3H2(g) ⇌ 2NH3(g)            K c = 3.7 × 108 (at 298 K)

c. N2(g) + O2(g) ⇌ 2NO (g)               K  c = 4.10 × 10−31 (at 298 K)
