C is necessarily not true because at equilibrium, only the rates of the forward and reverse reaction are the same. Concentrations and amounts of both reactants and products do not have to be the same at equilibrium

21.7 mL of gas at 98.8 kPa is allowed to expand at constant
IRISSAK [1]

Answer: 40.68 kPa

Explanation:

Given that,

Original volume of gas V1 = 21.7 mL

Original pressure of gas P1 = 98.8 kPa

New volume of gas V2 = 52.7 mL

New pressure of gas P2 = ?

Since pressure and volume are given while temperature is constant, apply the formula for Boyle's law

P1V1 = P2V2

98.8 kPa x 21.7 mL = P2 x 52.7L

2143.96 kPa L = 52.7 L x P2

P2 = 2143.96 kPa L / 52.7 L

P2 = 40.68 kPa

Thus, the new pressure of the gas is 40.68 kPa.
