Answer to Question #208159 in General Chemistry for mel

Question

Consider the reaction described by the equation

C₂H₄Br₂(aq)+3I^-(aq) ------> C₂H₄(g)+2Br^-(aq)+I^-₃(aq)

The rate law is

rate = k[C₂H₄Br₂][I^-]

where k = 0.00599 M^-1 s^-1

what are the missing entries in the table?

Run / [C₂H₄Br₂]₀ (M) / [I^-]₀ (M) / initial rate of formation of C₂H₄ (M s^-1)

1 / x / 0.156 / 0.000583

2 / 0.156 / y / 0.000292

3 / 0.156 / 0.156 / z

find x, y, z

Answer 1

$0.000583= (0.00599 × 0.156)X$

$X= 0.692 M$

$0.000292=(0.00599×0.156)y$

$y = 0.312M$

$Z=0.00599×(0.156)^2=0.000146$
