Homework Help: Chemistry(Please check answer)

Posted by Hannah on Wednesday, March 14, 2012 at 8:30pm.

The equilibrium constant for the reaction,
H2(g) + I2(g) == 2 HI(g) is 54.9 at 699.0 K (Kelvin).
What is the equilibrium constant for
4 HI(g) == 2 H2(g) + 2 I2(g) under the same conditions?

Note: the == indicates the equilibrium double arrow

Since the second equation is doubled I multiplied 54.9 by 2 and got 109.8. Is this correct??
