Ethanol (C2H5OH) melts at -114 °C. The enthalpy of fusion is 5.02 kJ/mol. The specific heats of solid and liquid ethanol are 0.97 J/g-K and 2.3 J/g-K, respectively.
What is the limiting reactant when equal masses of iron(III) nitrate and potassium phosphate react in solution?
reaction begins only after a collision between the reactants. So this is an endothermic reaction, and most reactions occur when two reactants collide with each other.
