This reaction is first order with respect to N2O5. 2 N2O5(g) → 4 NO2(g) + O2(g). If the half-life for this reaction is 19,0 minutes, what is the rate constant, k? a) 0.0158 min–1 b) 0.0263 min–1 c) 0.0365 min–1 d) 0.0526 min–1
Para determinar a constante de velocidade (k) de uma reação de primeira ordem, podemos usar a fórmula:
k = 0.693 / t1/2
Dado que o tempo de meia-vida (t1/2) é de 19,0 minutos, podemos calcular k:
k = 0.693 / 19,0
k ≈ 0,0365 min⁻¹
Portanto, a alternativa correta é:
c) 0,0365 min⁻¹
0
0
