Please explain how the calorimetry " -qrxn = qH20 + qcal" equation works and also generally which equations are used in constant pressure calorimetry vs. constant volume calorimetry. I've seen numerous variations and I'm not sure how to categorize them. Thanks.
consider the following reaction: 2 A(g) + B(g) 3 C(g) + D(g) Please determine Kc if 6.0 moles of A is added to 6.0 moles of B in a 2.0 L yields 0.10 moles of D at equilibrium.
