Calculate the reaction enthalpy, Delta H, for the following reaction: CH_4(g) + O_2(g) to CO_2(g) + 2H_2O(l) The reaction 2CH_4 (g) rightleftharpoons C_2H_2 (g) + 3H_2(g), K=0.135 at 1623 degrees C. What is K_p ...
Enthalpy is the thermodynamic function that describes heat flow. The calculation of the heat that is gained or lost can be determined by using the formula q = nCΔT. A negative result indicates that heat is lost when the reaction takes place, and a posit
