Please help with question 3
b. CH4(g)+2O2(g) CO2(g) +2H2O(g) c. P4(s)+502(g)=P4O10(S) CHICOO d. CO2(g) +2NaOH(s) Na₂CO3(s)+H₂O(g) 2. Gaseous phosphorus pentachloride decomposes according to the reaction PCIs(g) PC13(g)+Cl2(g) a. The equilibrium system was analyzed at a particular temperature, and the concentrations of the substances present were determined to be [PCIs] =1.1x10-²M, [PC3]=0.325M, and [Cl2]=3.9x10-³M. Calculate the value of K for the reaction. b. Using your value of K, determine the concentration of [Cl2] present when [PCIs] =5.0× 10-³M and [PC13] -0.225M. 3.
