Answer: False

Explanation:

An acid is defined as the substance which looses hydrogen ion or hydronium ions when dissolved in water.

A base is defined as the substance which looses hydroxide ions when dissolved in water.

If the solution has higher hydronium ion concentration as compared to the hydroxide ion concentration, then the pH will be low and the solution will be acidic.

If the solution has low hydronium ion concentration as compared to the hydroxide ion concentration then the pH will be high and the solution will be basic.

Determine the change in entropy for 2.7 moles of an ideal gas originally placed in a container with a volume of 4.0 L when the c
olchik [2.2K]

Answer:

The value of entropy change for the process dS = 0.009 \frac{KJ}{K}

Explanation:

Mass of the ideal gas = 0.0027 kilo mol

Initial volume V_{1} = 4 L

Final volume V_{2} = 6 L

Gas constant for this ideal gas ( R ) = R_{u}  M

Where R_{u} = Universal gas constant = 8.314 \frac{KJ}{Kmol K}

⇒ Gas constant R = 8.314 × 0.0027 = 0.0224 \frac{KJ}{K}

Entropy change at constant temperature is given by,

dS = R  log _{e} \frac{V_{2}}{V_{1}}

Put all the values in above formula we get,

dS = 0.0224  log _{e} [\frac{6}{4}]

dS = 0.009 \frac{KJ}{K}

This is the value of entropy change for the process.
