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

The rate constant for the reaction is

Explanation:

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

where,

k = rate constant

t = age of sample = 559 min

a = let initial amount of the reactant =

a - x = amount left after decay process  =

The rate constant for the reaction is

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
