Which of the following endothermic processes are spontaneous

The unit of entropy is

(a) J mol^-1
(b) JK mol^-1
(c) J mol^-1K^-1
(d) J^-1K^-1mol¹

The molar heat capacity of water at constant pressure is
75 JK^-1mol ^-1 . When 1.0 kJ of heat is supplied to 100g of
water which is free to expand the increase in temperature of
water is

What is the entropy change (in JK^-1 mol ^-1 ) when one mole of
ice is converted into water at 0^oC (The enthalpy change for the
conversion of ice to liquid water is 6.0 kJ mol^-1 at 0^oC )

Considering entropy (S) as a thermodynamic parameter, the
criterion for the spontaneity of any process is
