The reaction N_(2)O_(5) (in C Cl_(4) solution ) to 2 NO_(2) (solution) + (1)/(2) O_(2) (gas ) is of first order in N_(2)O_(5) with rate constant 6.2 xx 10^(-1) s^(-1) . What is the value of rate of reaction when [N_(2)O_(5)] = 1.25 "mole" l^(-1)

Answer»

`7.75 xx 10^(-1) "MOLE" l^(-1) s^(-1)`
`6.35 xx 10^(-3) "mole" l^(-1) s^(-1)`
`5.15 xx 10^(-5) "mole" l^(-1) s^(-1)`
`3.85 xx 10^(-1) "mole" l^(-1) s^(-1)`

SOLUTION :Rate = `k (N_(2)O_(5)) = 6.2 xx 10^(-1) xx 1.25`
= `7.75 xx 10^(-1)` mol `l^(-1) s^(-1)`.
