From the rate expression for the following reactions, determine their order of reaction and the dimensions of the rate constants. 3NO_((g))rarr N_(2)O_((g))" Rate"=K[NO]^(2)

Answer»

Solution :Given RATE `= K[NO]^(2)`
`THEREFORE` order of the REACTION = 2
`K = ("Rate")/([NO]^(2))`
Dimension of `=("MOL L"^(-1)S^(-1))/(("mol L"^(-1))^(2))`
`= ("mol L"^(-1)S^(-1))/(mol^(2)L^(-2))`
`= "L mol"^(-1)S^(-1)`.
