Ok what’s the question sir
Answer:
Explanation:
Hello!
In this case, since the differential rate law of a second-order reaction is:
Whereas A stands for NOCl and the corresponding integrated rate law is:
Thus, since we know the concentrations and the elapsed time, we compute the rate constant as shown below:
Best regards!
Actually Welcome to the Concept of the Chemical bonds.
Due to the presence of dipole-dipole forces, polar covalent molecules like water tend to be _____ at room temperature.
The answer is Liquids
Water tends to be liquids at the room temperature.
Answer:
52.9 KJmol-1
Explanation:
From;
log(k2/k1) = Ea/2.303 * R (1/T1 - 1/T2)
The temperatures must be converted to Kelvin;
T1 = 25° C + 273 = 298 K
T2= 35°C + 273 = 308 K
R= gas constant = 8.314 JK-1mol-1
Substituting values;
log 2 = Ea/2.303 * 8.314 (1/298 - 1/308)
Ea = 52.9 KJmol-1
