4 moles of Az (g) reacts completely with 2 moles of B2 (g) to form 4 moles of A;B (g) in a constant volume container at 75 °C. The heat released from this reaction increased the temperature of 38 g water by 14 °C. Calculate the enthalpy change of the reaction per mole consumption of B2 (g) as kJ with the sign. Do not write units, only enter numerical values. Use two digits at most for decimal numbers, use dot (.) as decimal separator (i.e. two-point-fifty-one should be entered as 2.51). Do not use comma () as decimal separator.

Question
4 moles of Az (g) reacts completely with 2 moles of B2 (g) to form 4 moles of A,B (g) in a constant volume container at 75 °C. The heat released from this reaction increased the temperature of 38
g water by 14 °C. Calculate the enthalpy change of the reaction per mole consumption of B2 (g) as kJ with the sign.
Do not write units, only enter numerical values.
Use two digits at most for decimal numbers, use dot (.) as decimal separator
(i.e. two-point-fifty-one should be entered as 2.51). Do not use comma () as decimal separator.
