Question

Consider the reaction:
H2(g)+I2(g)2HI(g)
Complete the table. Assume that all concentrations are equilibrium concentrations in moles per liter, M.

Part A

Complete the first row of the table. Keq=?

Express your answer using three significant figures.

Part B

Complete the second row of the table. [H2] =?

Express your answer using two significant figures.

Part C

Complete the third row of the table. [HI] = ?

Express your answer using three significant figures.

T(C) [H2] [I2] [Hl] Keq 25 0.365 0.448 0.0962 _____ 340 _____ 0.0435 0.407 9.6 445 0.0585 0.0368 _____ 40.2

Explanation / Answer

Keq= [HI]2/[H2][I2]

A) (0.0962)^2 / 0.448*0.365 =0.056

B) 9.6 *0.0435 /0.407*0.407 = 2.52

C) root of(40.2 * 0.0585 * 0.0368) =0.294
