Isomerization of CH3NC occurs slowly when CH3NC is heated. CH3NC(g) → CH3CN (g) To study the rate of this reaction at 488 K, data on [CH3NC] were collected at various times. Analysis led to the graph below. In[CH₂NC) -4.0 -5.0 -6.0 -7.0 0 4000 8000 12,000 Time, seconds a What is the rate law for this reaction? zero order in CH₂NC first order in CH₂NC Osecond order in CH₂NC, second order in both CH3NC and CH, CN

What is the equation In [CH3 NC], In [CH3NC], In [CH3NC], for the straight line in this graph? In [CH, NC], kt kt In [CH₂NC), In [CH3NC] x kt In [CH₂NC), In [CH, NC], x kt = = Correct For the first-order reaction, the equation of the plot In [R], vs. t is: In [CH, NC], In [CH, NC], - kt Calculate the rate constant for this reaction. Rate constant 2 x 10-4 s Correct

Calculate the rate constant for this reaction. Rate constant = 2 x 10-4 s Correct For the first-order reaction, the equation of the plot In [R], vs. t is: In [CH₂NC), In [CH₂NC), kt = Thus, k is: k = -slope =-(-2x 10s¹)=2x 10-48-¹ How long does it take for half of the sample to isomerize? (k = 2 × 10 s¹) 3300 Correct Time required to isomerize half of the sample is called the half-life of the reaction. For the first-order reaction, 0.693 t1/2 = = 3 x 10³ s What is the concentration of CH-NC after 1.0 x 10 s?

Time required to isomerize half of the sample is called the half-life of the reaction. For the first-order reac t1/2 0.693 k Correct = 3 × 10³ s Submit What is the concentration of CH, NC after 1.0 × 10¹ s? Concentration=1 mol/L
