1.	Reaction between red phosphorus and liquidbromineis an exothermic reaction represented as follows: 2P (s) +3Br_(2)(l) rarr 2P Br_(3)(g),DeltaH^(@) = - 243kJ mol^(-1) What will be the enthalpy change when 2.63g of phosphorusreacts accordingto the above reaction. Take atomic mass of phosphorus as 31.0 .
Answer» SOLUTION :REQUIRED `Delta H = ( 243 ) /( 62)xx 2.63 J = 10.3 kJ`
