What is the equilibrium constant for the reaction at 644 K ? What is the equilibrium constant for the reaction at 644 K ? The equilibrium constant, Kfor the following reaction is 1.55x0 at 644 When a sufficientiy large sample of HI(g) is introduced into an evacuated vessel at 644 K, the equilibrium concentration of I2)s found to be 0.303 M Calculate the concentration of HI in the equilibrium mixture. more group attempts remaining Submit Anawer Retry Entire Group Consider the following reaction where K 0.159 at 723 K. A reaction mixture was found to contain 2.07x102 moles of N2), 4.45x10-2 moles of H2) and 6.80x10-* moles of NH3() in a 1.00 liter container. Is the reaction at equilibrium? If not, what direction must it run in order to reach equilibrium? The reaction quotient,equals The reaction A. must run in the forward direction to reach equilibrium. B. must run in the reverse direction to reach equilibrium. Submit Anawer Retry Entre Group more group attempte remalining
