Answer:
The amount of C2H4I2 produced is maximized if
-Adding C2H4 to the reaction mixture
-Decreasing the reaction volume
-Also can include: raising the reaction temperature
Answer:
2+
Explanation:
Nickel has an atomic number of 28 meaning that it contains 28 protons in its nucleus. It would need 28 electrons in order to have no charge, because the positive and negative charges balance each other out. Since this atom of Ni has 26 electrons, it has lost 2 of its electrons, and therefore has a positive charge of 2.
Answer : The value of activation energy for this reaction is 108.318 kJ/mol
Explanation :
The Arrhenius equation is written as:

Taking logarithm on both the sides, we get:
............(1)
where,
k = rate constant = 
Ea = activation energy = ?
T = temperature = 435 K
R = gas constant = 8.314 J/K.mole
A = pre-exponential factor = 
Now we have to calculate the value of rate constant by putting the given values in equation 1, we get:


Therefore, the value of activation energy for this reaction is 108.318 kJ/mol
