The shells of marine organisms contain calcium carbonate CaCO₃ (m = 100.9 g/mole), largely in a crystalline form known as calcite. What pressure must be achieved to induce the conversion of calcite to aragonite at T = 298 K? Assume both calcite and aragonite are incompressible at T = 298 K. Options: A. 298 kPa B. 100.9 atm C. Not enough information D. Pressure is irrelevant in this context
