Kinetics Which of the following is true? In a reaction mechanism an intermediate is identical to an activated complex. Since intermediate compounds can be formed the chemical equations for the elementary reaches in a multistep mechanism do not always have to add to give the chemical equation of the overall process. If we know that a reaction is an elementary reaction, then we know its rate law. The rate-determining step of a reaction is the rate of the fastest elementary step of its mechanism All of the above

indium, and thallium have three electrons i think

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

c, liquids evaporate, creating a gas
