Question

a) For the reaction, 4Al(s) + 302(g) → 2 Al203 (s), the entropy change
is - 550 JK mol at 298 K. Inspite of the negative entropy change,
why is the reaction spontaneous? Given AH° = - 1650 kJ/mol.
b) An iron block at a temperature of 130°C loses 340J of heat to the
surroundings which are at room temperature of 32 °C. Calculate
i) The entropy change of the system(iron block)
11 The entropy change in the surrounding
111) The total entropy change in the universe due to this process.​
