Question

If the combustion of 1g of graphite produces 20.7 kJ of heat, what will be molar enthalpy change? Give the significance of sign also., ∆H = – 2.48 × 10 3 kJmol –1 , Negative value of ∆H ⇒ exothermic rxn, ∆H = – 2.48 × 10 2 kJmol –1 , Negative value of ∆H ⇒ exothermic reaction, ∆H = – 2.48 × 10 2 kJmol –1 , Negative value of ∆H ⇒ endothermic reaction, ∆H = – 3.67 × 10 2 kJmol –1 , Negative value of ∆H ⇒ exothermic reaction

MARKS App · Accepted Answer

Correct Option is : (B) ∆H = – 2.48 × 10 2 kJmol –1 , Negative value of ∆H ⇒ exothermic reaction
