Hydrogen peroxide decomposes to water and oxygen at constant pressure by the following reaction:

2 H2O2(l) → 2 H2O(l) + O2(g) ΔrH = -196 kJ

Calculate the value of q (kJ) in this exothermic reaction when 4.00 g of hydrogen peroxide decomposes at constant pressure?
◦ -23.1 kJ
◦ -11.5 kJ
◦ -0.0217 kJ
◦ 1.44 kJ
◦ -2.31 × 104 kJ
