For the gaseous reaction: N_(2)O_(4) rarr 2NO_(2)

Findingf concentration and time : The rate constant for the decomposition of gasous N_(2)O_(5) at 55^(@)C is 1.7xx10^(-3)s^(-1) . If the initial concentration of N_(2)O_(5) after five half-lives ? How long will it take for the N_(2)O_(5) concentration to fall to 12.5% of its initial values ? Strategy : Because the unit of rate constant is time^(-1) , the decomposition of N_(2)O_(5) is a first order reaqction. To find [N_(2)O_(5)] after n half lives, multiply its initial concentration by (1//2)^(n) since [N_(2)O_(5)] drops by a factor of 2 during each successive haslf-life.

The thermal decomposition of N_(2)O_(5) occues as: 2N_(2)O_(5) rarr 4NO_(2)+O_(2) Experimental studies suggest that rate of decomposition of N_(2)O_(5) rate of formation of NO_(2) or rate of formation of O_(2) all becomes double if concentration of N_(2)O_(5) is doubled. If rate of formation of O_(2) is 16 g//hr then rate of decomposition of N_(2)O_(5) and rate of formation of NO_(2) respectively is

The reaction, 2N_(2)O_(5)rarr 4NO_(2)+O_(2) , shows an increase in concentration of NO_(2) by 20xx10^(-3) mol litre^(-1) in 5 second. Calculate: (a) rate of appearance of NO_(2) , (b) rate of reaction and (c ) rate dissappearance of N_(2)O_(5) .
