Question

Time required to decompose `SO_(2)Cl_(2)` to half of its intial amount is `60 mi n.` If the decomposition is a first order reaction, calculate the rate constant of the reaction.

Answer 1

For the first order reaction,
Rate constant (k) `= (0.693/t_(1//2)) = 0.693/(60 min)`
`= 0.693/(60 xx 60s) = 1.9825 xx 10^(-4)s^(-1)`
