Initially the concentrations of [H2]= 4.2 M ,[I2] = 5.0 M and [HI] = 1.0 M are in an sealed vessel at 500K. At equilibrium, the concentration of [H2]= 0.6 M. What is the EQUILIBRIUM concentration for [H2],[I2]and [HI]? H2(g) + I2(g) 2 HI(g) [HI] =__M [H2] =___M [I2] =___M

The air pollutant NO is produced in automobile engines because of the high-temperature reaction below. If the initial concentrations of N2 and O2 at 1000 K are both 1 M, what are the concentrations of NO, N2, and O2 when the reaction mixture reaches equilibrium? Assume the product concentration...
