Question

Consider the following reaction: P4(g) +5O2(g) <--> P4O10(s) If the intial concentration of O2(g) is 1.0M and "x" is theequilibrium concentration of O2(g) what is the correct equilibriumrelation? A) Kc=5x^6 B) Kc=5/x^6 C) Kc= x^6 D) Kc=1/x^6 E) Kc=1/x^5 Consider the following reaction: P4(g) +5O2(g) <--> P4O10(s) If the intial concentration of O2(g) is 1.0M and "x" is theequilibrium concentration of O2(g) what is the correct equilibriumrelation? A) Kc=5x^6 B) Kc=5/x^6 C) Kc= x^6 D) Kc=1/x^6 E) Kc=1/x^5

Explanation / Answer

                                     P4(g)+5O2(g) <--> P4O10(s)                                                                               Kc = [P4O10] / [P4][O2]5 Given that initiallly 1.0 M of O2(g) is present and atequilibrium x M of O2(g) is present. Here relation is asked to express in terms of O2(g).As itis in the denominator part , Kc = 1 / (x) ^ 5 by neglectingthe remaining concentration terms.
