5. Two reactants combine to form a product in the reaction A + B -> C. The rate of the reaction depends on the concentrations of both reactants squared (rate = k[A]2 [B]2). What's the total reaction order of this reaction?
A. 4
B. 1
C. 2.
O D.3

C. 2.

Explanation:

The total reaction order of this reaction is second order (2). For a second order reaction ,the rate  depends on two variable concentration terms which may or may not be same.

Given that:

Two reactants combine to form a product in the reaction  A + B → C

The above reaction is bimolecular as two molecules are involved in the reaction.

If and are the concentrations of A and B respectively at any time t, then assuming  that the reaction is of first order with respect to both A and B , the overall order is second and the reaction rate is given by:

where;

= specific rate constant for a second order reaction and becomes the rate of the reaction when both and are unity.

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
