The gas phase decomposition of sulfuryl chloride at 600 K SO2Cl2(g)SO2(g) + Cl2(g) is first order in SO2Cl2. During one experime

nt it was found that when the initial concentration of SO2Cl2 was 2.83×10-3 M, the concentration of SO2Cl2 dropped to 3.06×10-4 M after 559 min had passed. Based on this experiment, the rate constant for the reaction is min-1.

Answer: The rate constant for the reaction is 3.96\times 10^{-3}min^{-1}

Explanation:

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant

t = age of sample = 559 min

a = let initial amount of the reactant = 2.83\times 10^{-3}

a - x = amount left after decay process  = 3.06\times 10^{-4}

559min=\frac{2.303}{k}\log\frac{2.83\times 10^{-3}}{3.06\times 10^{-4}}

k=\frac{2.303}{559}\log\frac{2.83\times 10^{-3}}{3.06\times 10^{-4}}

k=3.96\times 10^{-3}min^{-1}

The rate constant for the reaction is 3.96\times 10^{-3}min^{-1}

What is the bond order of c2−?express the bond order numerically?
diamong [38]
MO Diagram of C₂⁻ is shown below, 

Bond order is calculated as,

             Bond Order  =  [# of e⁻s in BMO]-[#of e⁻s in ABMO] / 2
Where,

BMO  = Bonding Molecular Orbital

ABMO  =  Anti-Bonding Molecular Orbital

Putting values,

             Bond Order  =  [9]-[4] / 2

             Bond Order  =  5 / 2

             Bond Order  =  2.5
