The following mechanism is given for the decomposition of nitryl chloride, NO_2Cl. Step 1: NO_2Cl rightarrow NO_2 + Cl Step 2: NO_2Cl + Cl rightarrow NO_2 + Cl_2 Identify the molecularity of the two steps. Step 1 is unimolecular Step 2 is unimolecular Step 1 is bimolecular: Step 2 is bimolecular Steps 1 and 3 are termolecular Step 1 is unimolecular. Step 2 is bimolecular. What is the overall reaction for the mechanism below? Enter the coefficients (0, 1, 2, 3, ..) for each substance listed below the mechanism. If a substance does not appear in the overall reaction, enter 0 (zero). I_2 doubleheadarrow 2I I + H_2 doubleheadarrow H_2I H_2I + I rightarrow 2HI I_2 I H_2 H_2 I HI
Expert Answer
Question 1
Molecularity of the reaction is number molecule is invoved to for the desired product
Unimolecular reaction is only one molecule involved in product formation.
Therefore step one is unimolecular
In step 2 two molecule is invvolved to form products
Therefore answer is step 1 is unimolecular . Step 2 is bimolecular
Question 2
Overall reaction
H2 + I2 ———–> 2 HI
Coefficient for I2 is 1
Coefficient for I is 0
Coefficient for H2 is 1
Coefficient for H2I is 0
Coefficient for HI is 2
