Gibbs energy change $$\Delta $$G is related to equilibrium constant K as:

Which of the following relation is incorrect?

Assertion (A): The value of $$\Delta E$$ is negative if the internal energy of a system increases. 

Reason (R): The value of $$Q$$ is negative if heat is absorbed by the system.

A heat engine absorbs heat $$Q_{1}$$ at temperature $$T_{1}$$ and heat $$Q_{2}$$ at temperature $$T_2$$ . Work done by the engine is $$(Q_{1}+Q_{2}) J$$ . This data:
