What happens to the concentration of the reactants and products during the course of a forward chemical reaction
chubhunter [2.5K]
Hello!

The concentration of the reactants decreases and the concentration of products increases during the course of a forward chemical reaction.

A chemical reaction is a thermodynamical process in which two or more substances (called reagents) undergo transformation by the breaking and rearrangement of their chemical bonds to form another substance(s), called products. In a forward chemical reaction, the reagents are being consumed, so their concentration will decrease, increasing the concentration of products as they are the result of the reaction. 

The study of how concentration changes with time in a chemical reaction is called reaction kinetics. 

Have a nice day!

Boyles Law P1V1 = P2V2
arsen [322]

Answer:

A. The balloons will increase to twice their original volume.

Explanation:

Boyle's law states that the pressure exerted on a gas is inversely proportional to the volume occupied by the gas at constant temperature. That is:

P ∝ 1/V

P = k/V

PV = k (constant)

P = pressure, V = volume.

P_1V_1=P_2V_2

Let the initial pressure of the balloon be P, i.e. P_1=P, initial volume be V, i.e. V_1=V. The pressure is then halved, i.e. P_2=\frac{P}{2}

P_1V_1=P_2V_2\\\\P*V=\frac{P}{2} *V_2\\\\V_2=\frac{2*P*V}{P}\\\\V_2=2V

Therefore the balloon volume will increase to twice their original volume.
