Consider the rate law below.
Inessa [10]
If you double the concentration of A, the rate is doubled. If you doubled the concentration of B, since the rate law has B^2, the rate is multiplied by 4. If you double both A & B's concentrations, then the rate would be multiplied by 2*4 = 8, which is the last option.

Which types of atomic orbitals of the central atom mix to form hybrid orbitals in:<br> (c) PF₅;
zloy xaker [14]

The atomic orbitals of the central atom mix to form hybrid orbitals are one s and three p.

<h3>Which atomic orbitals are used to form hybrid orbitals?</h3>

Pauling supposed that in the presence of four hydrogen atoms, the s and p orbitals form four equivalent combinations which he called hybrid orbitals.

<h3>How many bonds does PF5?</h3>

Phosphorus pentafluoride has 5 regions of electron density around the central phosphorus atom (5 bonds, no lone pairs).

The resulting shape is a trigonal bipyramidal in which three fluorine atoms occupy equatorial and two occupy axial positions.
