Answer : The rate constant for this reaction at 384.7 K is,
Explanation :
The relation between frequency factor, rate constant and activation energy for a chemical reaction is,
where,
k = rate constant = ?
A = frequency factor =
Ea = activation energy = 12.9 kJ/mol
T = temperature = 384.7 K
Now put all the given values in this formula, we get:
Therefore, the rate constant for this reaction at 384.7 K is,
Answer:
true
Explanation:
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
The answer is 2.5 times heavier than on Earth !!
so the answer is C !!
