Example for first order reaction.

Text Solution

Verified by Experts

1. Decomposition of nitrogen pentaxide `(N_2O_3)`
`N_2O_5(g) to 2NO_(2(g)) + 1/2 O_2(g)`
Rate = `k[N_2O_5]`
2. Reaction of second order
`2NO_2 to 2NO_2 + O_2`
3. Reaction for third order
`H_2 + I_2 + 2 HI k [H_2][I_2]` = Rate
4. Reaction of fractional order
`CH_3CHO to CH_4 + CO_2`
Rate = `k[CH_3CHO]^(3//2)`
Order `= 3/2 = 0.5 + 1`
`= 1.5 `
