- A flask is charged with 1.720 atm of N₂O4(g) and 0.88 atm NO₂(g) at 25°C. The equilibrium reaction is given in the equation below. N₂04(9) 2NO₂(g) After equilibrium is reached, the partial pressure of NO₂ is 0.512 atm. (a) What is the equilibrium partial pressure of N₂O4? 1.904 atm (b) Calculate the value of K, for the reaction. 0.137 (c) Is there sufficient information to calculate K for the reaction? O Yes, because the partial pressures of all the reactants and products are specified. Ⓒ Yes, because the temperature is specified. O No, because the value of K. can be determined experimentally only.
