I If a chemical system is at equilibrium, any change in the system will always result in an increase of which of the following? 1.The reaction that opposes the change

2. The concentration of the product

3. The concentration of the reactants

4. The temperature of the system​

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
