Which best describes a key difference between critical thinkers and uncritical thinkers, according to Chaffee?

The balanced equation for a given reaction is X + Y → P. The following data regarding initial reaction rates were collected in the lab. Fill in the blanks regarding this reaction by typing the correct number without units. Trial [X] (M) [Y] (M) Rate (M/s) 1 0.020 0.060 3.40 x 10–3 2 0.020 0.120 2.72 x 10–2 3 0.080 0.060 1.36 x 10–2 What is the order with respect to X? _______ What is the order with respect to Y? _______ What is the overall order of the reaction? _______ What is the rate constant, k, written to 3 significant figures? _______

Nitrosyl chloride (NOCl) decomposes in a second order reaction. At 425°C, the rate constant is {k} x 10–4 M–1min–1. If the initial concentration of NOCl is {M0} M, what will be the concentration after {t} minutes? For full credit Report your answer rounded to two decimal places.  Ex:  3.210 = 3.21 Include the correct unit.  

BONUS Calculate the activation energy (in kJ) for a given reaction using the data in the chart below.  The rate constants were measured at two different temperatures in K.   Trial Rate constant Temperature (K) 1 {k1} x 10–4 {T1} 2 {k2} x 10–2 {T2} For full credit Report your answer rounded to one decimal place.  Ex:  43.21 = 43.2 Include the correct unit. Additional information you may or may not need: R = 8.314 J/(K*mol)

What is E°cell for the reaction below? Do not use the REAL values for these species Sn 4+ (aq) + 2 K (s)  ⇌  Sn 2+ (aq) + 2 K + (aq) For full credit Report your answer with 4 significant figures. Include the correct unit. Additional Information you may need for this problem: Assume standard conditions Do not use the REAL values for these species; instead use these: Sn 4+ (aq)  ⇌  Sn 2+ (aq)   Ered = {Sn} V 2 K (s)  ⇌  2 K + (aq)  Ered = – {K} V

A certain second order reaction has a rate of {r1} M/s when the concentration of reactant A is 0.25 M. What is the rate for this reaction of the concentration of A is 1.5 M? Format your answer: Enter your answer to two decimal places. Include the correct unit
