G The gas phase decomposition of sulfuryl chloride at 600 K SO2Cl2(g) SO2(g) + Cl2(g) is first order in SO2Cl2 with a rate constant of 2.80×10-3 min-1. If the initial concentration of SO2Cl2 is 2.86×10-3 M, the concentration of SO2Cl2 will be M after 720 min have passed.

Answer : The concentration of SO₂Cl₂ after 720 min will be,

Explanation :

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

where,

k = rate constant  =

t = time passed by the sample  = 720 min

a = initial amount of the reactant  =

a - x = amount left after decay process = ?

Now put all the given values in above equation, we get

Therefore, the concentration of SO₂Cl₂ after 720 min will be,

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
