A solution of 500 mL of 2M KOH is added to 500 mL of 2M HCl and the mixture is well shaken. The rise in temperature is noted. The experiment is then repeated using 250 mL of each solution and rise in temperature is again noted. Assume all heat is taken up by the solution:
View answer and explanation
Correct option: A
=
Option A (T1=T2) is correct because the heat released per mole of reaction is the same in both cases, and the total volume of solution is also the same, leading to the same temperature rise.

The internal energy of one mole of a gas is:
An ideal gas is allowed to expand both reversibly and irreversibly in an isolated system. If is the initial temperature and is the final temperature, which of the following statements is correct?
For which of the process, ∆S is negative?
The work done by a weightless piston in causing an expansion ∆V (at constant temperature), when the opposing pressure, P is variable, is given by:
Assertion :- At constant pressure of the change work done is negative.
Reason :- During phase transition work done is always negative. For the reaction, at . Hence, is
