WebJun 5, 2024 · We have identified three criteria for whether a given reaction will occur spontaneously (that is, proceed in the forward direction, as written, to reach equilibrium): ΔS univ > 0, ΔG sys < 0, and the relative magnitude of the reaction quotient Q versus the equilibrium constant K. Recall that if K > Q, then the reaction proceeds spontaneously to …
WebQ1. What is the value of gravitational constant G . a) on the earth. b) on the moon. Answer: The value of gravitational constant G on the earth as well as on the moon = 6.67× 10-11 Nm 2 /kg 2. The value of G always remains constant irrespective of the location. Q2. When an object is dropped from a height, it accelerates and falls down. The measured value of the constant is known with some certainty to four significant digits. In SI units, its value is approximately 6.674 × 10−11 m3⋅kg−1⋅s−2. [1] The modern notation of Newton's law involving G was introduced in the 1890s by C. V. Boys. See more The gravitational constant (also known as the universal gravitational constant, the Newtonian constant of gravitation, or the Cavendish gravitational constant), denoted by the capital letter G, is an empirical physical constant involved … See more The gravitational constant is a physical constant that is difficult to measure with high accuracy. This is because the gravitational force is an extremely weak force as compared to other fundamental forces at the laboratory scale. In See more A controversial 2015 study of some previous measurements of G, by Anderson et al., suggested that most of the mutually exclusive values in high-precision measurements of G can be explained by a periodic variation. The variation was … See more According to Newton's law of universal gravitation, the attractive force (F) between two point-like bodies is directly proportional to the product of their masses (m1 and m2) and See more Early history The existence of the constant is implied in Newton's law of universal gravitation as published in the 1680s (although its notation as G dates … See more • Physics portal • Gravity of Earth • Standard gravity • Gaussian gravitational constant See more • Newtonian constant of gravitation G at the National Institute of Standards and Technology References on Constants, Units, and Uncertainty • The Controversy over Newton's Gravitational Constant — additional commentary on measurement problems See more
WebDec 8, 2015 · Yes, at equilibrium, ΔrG = 0 and Q = K. However, everything after the first bullet point is wrong. You cannot conclude that ΔrG ∘ = 0, nor can you conclude that K = 1. The equation ΔrG ∘ = − RTlnK does not analogously translate into ΔrG = − RTlnQ! The accurate relation is: ΔrG = ΔrG ∘ + RTlnQ.
