When 25.0 ml of 0.500 m h2so4 is added to 25.00 mk of 1.00 m koh in a coffee-cup calorimeter at 23.50◦ c, the temperature rises to 30.17◦ c. calculate dhrxn for this reaction. (assume that the density of water of and specific heat capacity of the solution are the same as for pure water). ( –55.8 kj/mol koh, –112 kj/mol h2so4)
