A 0.1329 g sample of solid magnesium is burned in a constant-volume bomb calorimeter that has a heat capacity of 1769 J/°C. The calorimeter contains exactly 251 g of water, and the temperature increases by 1.126°C. Compute the heat given off by the burning Mg, in kJ/g and in kJ/mol.
The true rate constant for a reaction is just that, a constant( at the constant temperature). Would your calculated value for k be higher than, lower than, or equal to the real value of k if 5 wt% bleach was unknowingly substituted with 8wt% bleac..
