Write qc for each of the following: (1) gaseous sulfur tetrafluoride reacts with liquid water to produce gaseous sulfur dioxide and hydrogen fluoride gas. (2) solid molybdenum(vi) oxide reacts with gaseous xenon difluoride to form liquid molybdenum(vi) fluoride, xenon gas, and oxygen gas.

Answer : The expression for reaction quotient will be :

(1)

(2)

Explanation :

Reaction quotient : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.

(1) The given balanced chemical reaction is,

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.  So, the expression for reaction quotient will be :

(2) The given balanced chemical reaction is,

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
