ITEM 18 The reaction X2(g)?2X(g) occurs in a closed reaction vessel at constant volume and temperature. Initially, the vessel contains only X2at a pressure of 1.90atm . After the reaction reaches equilibrium, the total pressure is 2.65atm .What is the value of the equilibrium constant, Kp, for the reaction?
X | ||
Initial pressure (atm) | 1.90 | 0 |
Equilibrium pressure (atm) | 1.90-x | 2x |
The equilibrium total pressure is 2.65 atm.
Hence,
Hence, the equilibrium pressures of X2 and X are and respectively.
The expression for the equilibrium constant is
Substitute values in the above expression.
