The favourable conditions for a spontaneous reaction are
Cell A, B and C are present in a sequence. The Psi values of these cells are -3, -6 and -10 MPa respectively. What is the direction of water flow among the cells ?
For a cell, the graph between the p.d.(V) across the terminals of the cell and the current I drawn from the cell is shown in the fig. the emf and the internal resistance of the cell is E and r respectively.
The change in Gibbs free energy of the system along provides a criterion for the spontaneity of a process at constant temperature and pressure. A change in the free energy of a sytem at constant temperature and pressure will be: DeltaG_("system") = DeltaH_("system") - T DeltaS_("system") For a spontaneous reaction DeltaG , equilibrium constant K and E_("cell")^(0) will be respectively:
