HI dissociates to form I₂ and H₂:
2HI(g) $\rightarrow$ H₂(g) + I₂(g)
If the concentration of HI changes at a rate of -0.45 M/s, what is the rate of appearance of I₂(g) ?

HI dissociates to form I₂ and H₂: 2HI(g) $\rightarrow$H₂(g) + I₂(g) If the concentration of HI changes at a rate of -0.45 M/s, what is the rate of appearance of I₂(g)?

Quizplus · Accepted Answer

From the balanced chemical equation, the stoichiometric coefficient of I₂(g) is 1, which means the rate of appearance of I₂(g) is also -0.45 M/s. However, the question asks for the absolute value of the rate, so the answer is 0.45 M/s.
