Answer to Question #169449 in Chemistry for Phyroe

Question

Predict the effect of an increase in pressure upon each of the following gaseous equilibria:

(a) 2PH3 + 6Cl2⇌2PCl3 + 6HCl

(b) 2NO + O2⇌2NO2

(c) CO2 + H2⇌CO + H2O

(d) N2 + O2⇌2NO

(e) CH4 + H2O⇌CO + 3H2

Answer 1

a) 2PH₃ + 6Cl₂⇌2PCl₃ + 6HCl - increased pressure accelerates forward reaction

(b) 2NO + O₂⇌2NO₂ - increased pressure accelerates forward reaction

(c) CO₂ + H₂⇌CO + H₂O - increased pressure does not impact the reaction equilibria

(d) N₂ + O₂⇌2NO - increased pressure does not impact the reaction equilibria

(e) CH₄ + H₂O⇌CO + 3H₂ - increased pressure accelerates the reverce reaction
