Answer:
1) The reaction rate is double with respect to that reactant
Explanation:
Hello,
By considering the rate law:

If we double the reactant A concentration, by definition, the rate will be doubled as well since the
power is one (order 1), this could be proved just by checking it out in the rate law.
Best regards.
Answer:
Lewis structure in attachment.
Explanation:
Atoms of elements in and beyond the third period of the periodic table form some compounds in which more than eight electrons surround the central atom. In addition to the 3s and 3p orbitals, elements in the third period also have 3d orbitals that can be used in bonding. These orbitals enable an atom to form an <u>expanded octet</u>.
The central Xe atom in the XeF₄ molecule has <u>two</u> unbonded electron pairs and <u>four</u> bonded electron pairs in its valence shell.
