Thermal-energy reaction rate coefficients and product ion distributions have been measured for reactions of both the ground state and metastable electronic states of 0, N0and 0with several neutral species, using a selected-ion flow tube. In general the excited-ion reaction rates are fast, frequentl...
The rate constants of the radical–radical reaction OH(X)+NH(a)→products and the radical–molecule reaction OH(X)+HN3→products were determined in a quasistatic laser photolysis cell at room temperature and a total pressure of 20 mbar. The radicals OH(X) and NH(a) were generated by exci...
Chemical reaction rates are influenced by several factors. Temperature is one of the most important factors. As the temperature increases, the rate of a chemical reaction generally increases. This is because at higher temperatures, the molecules have more kinetic energy. They move faster and collide...
The experimental and calculated reaction rates of all the three reactions are in reasonably good agreement. The transmutation power, P norm as well as P norm / P beam of the set-up is estimated using the reaction rates of the (n, \\( \\gamma\\) and (n, 2n) reactions for both the...
29 In a chemical reaction, X reacts with Y to form Z. The initial rates of the reaction are shown for the following experiments:experiment[X]/ mol dm-3[Y]/ mol dm-3initial rate/ mol dm310.1500.2502.80*10^(-5) 20.1500.5005.60*10^(-5) 30.0750.5002.80*10^(-5) 40.0750.2501.40*10^...
The competing reaction was the reaction of the hydrated electron with the hydronium ion. The effect of the substituents on the rate constants was shown to be mainly of the inductive type. The reaction rates can be correlated by means of Taft's equation with positive slope ϱ ∗ = 1·94...
Reaction rate coefficients and thermodynamic and transport properties are provided for the 11-species air model which can be used for analyzing flows in chemical and thermal nonequilibrium. Such flows will likely occur around currently planned and future hypersonic vehicles. Guidelines for determining the...
