N<SUB>2</SUB>O decomposition and N<SUB>2</SUB>O–H<SUB>2</SUB> reaction were studied behind incident and reflected shock waves in the temperature range 1450–2200 K and pressure range 0.6–3.5 atm using both single-pulse and time-resolve techniques. A computer-simulation study was performed to determine the rate-constant expressions of important elementary reactions. Computer calculations showed that the values of the rate constant for N<SUB>2</SUB>O+O\xrightarrow<I>k<SUB>2</SUB></I>N<SUB>2</SUB>+O<SUB>2</SUB> and N<SUB>2</SUB>O+O\xrightarrow<I>k<SUB>2</SUB></I>NO+NO (cited in current papers) are too low. The rate-constant expressions were found to be <I>k</I><SUB>2</SUB>=7.0×10<SUP>14</SUP>exp(−28 kcal/<I>RT</I>) cm<SUP>3</SUP>mol<SUP>−1</SUP> s<SUP>−1</SUP> and <I>k</I><SUB>3</SUB>=5.6×10<SUP>14</SUP>exp (−28 kcal/<I>RT</I>) cm<SUP>3</SUP> mol<SUP>−1</SUP> s<SUP>−1</SUP>. The rate constant expression for N<SUB>2</SUB>O+H\xrightarrow<I>k<SUB>2</SUB></I>N<SUB>2</SUB>+OH, was found to be <I>k</I><SUB>4</SUB>=1.5×10<SUP>14</SUP>exp (−15 kcal/<I>RT</I>) cm<SUP>3</SUP> mol<SUP>−1</SUP> s<SUP>−1</SUP>.
