The reaction has stopped because all reactants have been used up. Which statement best describes evidence that a chemical reaction occurs as a cake bakes?A The water in the cake evaporates.B The cake rises as gas bubbles form in the baking cake.C The cake takes the shape of the container in which it is baked.D The water in the cake batter is used to keep the or D. The products have lower potential energy … Which statement describes a chemical reaction at equilibrium? B. They absorb oxygen from the enviornment. Some reactions appear to be “substitution” of an alkene, but in fact, is the result of an “addition-elimination” sequence of reactions. They decolourises bromine water. The catalyst binds to enzymes to release substrates. Which statement describes a chemical reaction at equilibrium? (1 point) A catalyst weakens the bonds of the reactants lowering the activation energy. The products have higher potential energy than the reactants, and the ΔH is negative. The catalyst increases the concentration of reactants. Which statement correctly describes an endothermic chemical reaction? a) Reactant molecules and product molecules have the same velocity. The reactants are what are "reacting". A catalyst strengthens the bonds of the reactants increasing the activation energy. (2) The concentrations of the products and reactants are constant. Which best describes a chemical reaction? Identify the statement which does not describe the property of alkenes. 3.they affect the rate of chemical reactions. The rearrangement of atoms constitutes a chemical reaction, although some phase changes can also qualify. B. Which statement correctly describes a chemical reaction? C. The products have lower potential energy than the reactants, and the ΔH is negative. O Reactants come out of a reaction. Clearly two of these can be eliminated. They are unsaturated hydrocarbons. The forward reaction happens slightly faster than the reverse reaction. 4. 2. they provide energy for chemical reactions. Energy is always released Bonds between atoms break and new bonds form. 10. 1. they control the transport of materials. Chemical reactions are an integral part of technology, of culture, and indeed of life itself.Burning fuels, smelting iron, making glass and pottery, brewing beer, and making wine and cheese are among many examples of activities incorporating chemical reactions that have been known and used for thousands of years. (3) The rate of the forward reaction is less than the rate of the reverse reaction. B. A. The catalyst makes lower energy pathways available. The products have higher potential energy than the reactants, and the ΔH is positive. (1) The concentrations of the products and reactants are equal. Aug 2002-13 Which statement correctly describes a chemical reaction at equilibrium? the rearrangement of atoms by breaking and reforming chemical bonds a reaction that absorbs heat from the surroundings a reaction that releases heat to the surroundings the rearrangement of molecules based on temperature and pressure Which statement correctly describes what transpires during a chemical reaction? Please put the number of the answer i … A. C. The forward reaction happens at the same rate as the reverse reaction. Products go into a reaction, Mark this and return Save and Exit Sube The catalyst increases the concentration of products. Which statement best describes how a catalyst can speed up a chemical reaction? Which statement correctly describes a chemical reaction?O Reactants come out of a reaction.O Energy is always released.O Bonds between atoms break and new bonds form.O Products go into a reaction. The products are what is formed. D. The reaction has stopped until a stress is applied to the system. The products don't react. Which statement describes all enzymes? A.
