Answer:
v = 3.60Lmol⁻¹s⁻¹ [NH₄CNO]²
Explanation:
The reaction at 65°C of ammonium cyanate to produce urea is:
NH₄CNO → NH₂CONH₂
The general rate law is:
v = K [NH₄CNO]ˣ
Where v is rate of the reaction, K is rate constant and x represents the order of reaction
Based on the units of the rate constant (Lmol⁻¹s⁻¹ = M⁻¹s⁻¹) the reaction must be order 2 and the rate law:
v = K [NH₄CNO]²
v = 3.60Lmol⁻¹s⁻¹ [NH₄CNO]²
