A)if it takes 0.20 min to decompose 15% of a 0.300 m solution of nitrosyl chloride, what is k(the rate constant)? the decomposition of nitrosyl chloride is a second order reaction: nocl(> no(g)+1/2cl2(g)b)calculate the activation energy? when the temperature increases from 15c to 25c for a certain reaction, its rate constant doubles. calculate the activation energy, ea+ (remember: with r=8.31 j/mol. k, ea must be expressed in j/mol)
