WebJan 2, 2024 · Solution . The equilibrium constant (K) for the chemical equation aA + bB ↔ cC + dD can be expressed by the concentrations of A,B,C and D at equilibrium by the equation K = [C] c [D] d /[A] a [B] b For this equation, there is no dD so it is left out of the equation. WebAug 2, 2024 · q = c_p \times m \times \Delta T \nonumber The heat that is either absorbed or released is measured in joules. The mass is measured in grams. The change in temperature is given by \Delta T = T_f - T_i, where T_f is the final temperature and T_i is the initial temperature.
WebJul 27, 2014 · If you want to calculate ΔG under non-standard conditions, you need to use the equation ΔG = ΔG0 +RT lnQ where Q is the ratio of concentrations (or activities) of the products divided by the reactants. Under standard conditions Q=1 and ΔG = ΔG0. Under equilibrium conditions, Q=K and ΔG = 0 so ΔG0 = −RT lnK. WebApr 14, 2015 · How can I find specific heat in thermochemistry of phase of changes?

WebJan 28, 2024 · Hi Grace! rev stands for reversible and you can get this value by solving for q (heat) in different ways depending on the problem you're being asked. For example, you might combine it with q = C delta T or if it's an isothermal reversible problem, then you can deduce change in internal energy (delta U) will be 0, so q = -w and you can combine ... WebQ = mc∆T. Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) What is Q for an ideal gas? Q = nCVΔT. For an ideal gas, applying the First Law of Thermodynamics tells us that heat is also equal to: Q = ΔEint + W, although W = 0 at constant volume. How do you find Q without C?
