Question

At 1002 K, Keq = 1.56e+00 for the reaction

IBr(g) 1/2 I2(g) + 1/2 Br2(g)

What is the value of Keq for the reaction I2(g) + Br2(g) 2 IBr(g) at this temperature?

a) For the second reaction at this temperature Keq = 4.09e-01.
b) For the second reaction at this temperature Keq = 8.01e-01.
c) For the second reaction at this temperature Keq = 2.45e+00.
d) For the second reaction at this temperature Keq = 1.25e+00.
e) For the second reaction at this temperature Keq = 6.41e-01.

Explanation / Answer

I2(g) + Br2(g) ---> 2 IBr(g) Keq = (1/1.56)^2 = 0.41 = 4.09e-01 a) For the second reaction at this temperature Keq = 4.09e-01.
