For the simple decomposition reactionab(g)→ a(g) + b(g)rate =k[ab]2 and k=0.2 l/mol*s . how long will it takefor [ab] to reach 1/3 of its initial concentration 1.50 mol/l?

6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.

Explanation:

The order of the reaction is 2.

Integrated rate law for second order kinetic is:

Where, is the initial concentration  = 1.50 mol/L

is the final concentration  = 1/3 of initial concentration = = 0.5 mol/L

Rate constant, k = 0.2 L/mol*s

Applying in the above equation as:-

6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
