Answer:

A. Occur in gaseous and liquid state

Explanation:

The choice that is not a characteristic of minerals is that minerals occur in gaseous and liquid state.

All minerals are solid inorganic compounds.

A mineral is an inorganic compound that is formed naturally.
They have a definite and specific chemical composition.
Minerals are the building blocks of rocks.
When minerals aggregates together, they form different rock types.
There is no known mineral that is in fluid state.
All minerals are solids.
Examples are quartz, kaolinite, gypsum e.t.c

write the overall rate law for the initial rate of the reaction as a fraction.

Rate=k(________/_________)

Answer:

The overall rate law for the initial reaction is = $k_{overall} [H_{2}SO_{4}]^{2} [C_{6}H_{6}]$

Explanation :

Frist of all, all the common terms are cancelled out and written the overall reaction.

As we know that the rate depednant step is the slowest step of the reaction, rate law is :

rate = $k_{2} [SO_{3}][C_{6}H_{6}]$

But the problem is that SO3 cannot be written in the overall rate law because it is an intermediate.

Rate law for synthesis of S03 is as follows :

rate = $k_{1}[H_{2}SO_{4}]^{2}$

Hence when we substitute equation 2 in equation one,

Rate comes out to be = $k_{overall} [H_{2}SO_{4}]^{2} [C_{6}H_{6}]$
