Please compute the right answer of the given problem
Question- The following reaction was performed in a sealed vessel at 775oC :
H2(g)+I2(g) = 2HI(g)
Initially, only H2 and I2 were present at concentrations of [H2]=3.40M and [I2]=2.65M. The equilibrium concentration of I2 is 0.0400M.
Part 1- What is the equilibrium constant, Kc, for the reaction at this temperature?
I need expert's assistance to find the equilibrium constant for the reaction at given temperature and express your answer numerically.
