Calculate AG for this reaction at 298 K. Number 234.4 kJ What can be said about the spontaneity of the reaction at 298 K? O O The system is spontaneous as written. The system is at equilibrium. The system is spontaneous in the reverse direction. O Previous # Try Again Next about us careers privacy policy terms of usecontact us he 0 F3 F5 F6 F7 F8 o/

Explanation / Answer

deltaG = deltaH - TdeltaS

= - 144.6 - 298( - 0.3012)

= - 54.84 kJ

Since deltaG is obtained a negative value, the reaction is spontaneous at 298 K as written.
