When `5mL` of a `1.0M HCl` solution is mixed with `5mL` of a `0.1M NaOH` solution, temperature of solution increases by `t^(@)C`. Which of the following(s) can be predicted from this observation

Options

A. If `5mL` of `0.1M HCl` is mixed with `5mL 0.1M NH_(3)` solution, the temperature rise will be less than `t^(@)C`
B. If `5mL 0.1M CH_(3)COOH` is mixed with `5mL 0.1 M NaOH`, the temperature rise will be less than `t^(@)C`
C. If `10mL` of `1.0M HCl` is mixed with `10mL` of `0.1M NaoH`, the temperature rise will be `2t^(@)C`
D. If `10 ML` of `0.1M HCl` is mixed with `10 mL` of `0.1 M NaCl` the temperature rise will be `t^(@)C`

Answer

A, B

Explanation

Reaction proceeds by limiting reagent only. Enthalpy of neutralization decreases, when acid or base or both are weak:
