Question
1. List all of the chemicals you will use for this week's experiment. For each chemical, list specitic safety precaution(s) that must be followed. In order to find specific safety information, please obtain a Materials Safety Data Sheet (MSDS) on the chemical of interest. MSDSs can be found through an internet search (e.g., google) or from the following website: www.hazard.com. Read the MSDS and find specific safety concerns for each chemical. List the chemicals you will use for the hands-on portion of this week's lab experiment. For each chemical, list specific safety precaution(s) that must be followed 2. What is the chemical equation for the reaction we will study in this week's experiment? 3. Define the word catalyst. What substance will be used as a catalyst in this week's experiment? 4. Write the rate law for the general reaction given by aA +bBcC+dD 5. Determine the rate of the chemical reaction 2NO+2H2N2 +2H20, given an NO concentration of 12.0 x 103 M, an H2 concentration of 3.0 x 10-3 M, and a rate constant k of 2.5 x 10 Ms The rate law for this reaction is rate k [NOJH2Explanation / Answer
Answer (3)
Catalyst :- It is a substance which can change the rate of reaction without itself being affected.
Answer (4) :- rate law:
Rate = r = k[A]m[B]n ; m = order of rxn w.r.t. A
n = order of rxn w.r.t. B
k = rate constant
m & n may or may not equal to a&b respectively.
Answer (5):
Rate = k[NO]2[H2]
= 2.5×10-2 ×(12×10-3)2 ×(3×10-3)
= 1.08×10-8 M/s
