Answer to Question #127592 in General Chemistry for Ni

Question

1. The reaction of 3.0 moles of H2 with 2.0 moles of I gives 1.0 mole of HI H2(g) I2(s) → HI(g) + Balance this equation, determine the limiting reactant, the theoretical yield in moles and the percent yield for this reaction.

Answer 1

H_2(g) + I_2(s) $\to$ 2HI_(g)

The limiting reactant is Iodine since not all its moles are used in the reaction.

Theoretical yield in moles is 2.

Percentage Yield

theoretical yield = 254

actual yield = 224

$224/ 254 * 100 = 88.19$

88.19%
