In $I^{st}$ experiment 200 mL of 0.1 M NaOH is mixed with 100 mL of 0.1 M $H_{2}S{O}_4.$ In $I{I}^{nd}$ experiment 100 mL of 0.1 M NaOH is mixed with 50 mL of 0.1 M $H_{2}S{O}_4.$ Select the correct statements if enthalpy of neutralization is $-13.7$ K cal.

1) Heat liberated in each of the two reactions is 274 cal

2) Heat liberated in I is 274 cal and in II is 137 cal

3) Temperature rise of mixture of $I^{st}$ experiment is more than that of $I{I}^{nd}$ experiment.

4) Temperature rise of mixture of $I^{st}$ experiment is same as that of $I{I}^{nd}$ experiment
