Example . . . Rate Expression and Rate Constant The decomposition of N O in CCl at 318K has been studied by monitoring the concentration of N O in the solution. Initially the concentration of N O is . mol L – and after minutes, it is reduced to . mol L – . The reaction takes place according to the equation N O (g) ® NO (g) + O (g) Calculate the average rate of this reaction in terms of hours, minutes and seconds. What is the rate of production of NO during this period? Average Rate = = − ( ) N O mol L . . min . × – mol L – /min = ( . × – mol L – min – ) × ( min/1h) . × – mol L – /h . × – mol L – × 1min/60s . × – mol L – s – It may be remembered that NO ∆ t NO . × – × mol L – min – = . × – mol L – min –
