Look at the diagram below that shows the reaction quotiant, Q for this reaction. A(s) + B(g) + 2C(aq) 2D(g) + E(aq) The reaction begins at equilibrium. There are 6 processes listed below that are applied individually to put a stress on the equilibrium. For each process, identify the position of Q that occurs immediately after the stress is applied. Then drag the purple number that identifies the process to the proper gray boxes in the graph. There can be more than 1 number in each gray box. The line marked K shows the initial equilibrium. 2 Some B is removed 4 Some E is removed Some A is added 3 Some D is added 5 Water is added. Gas volume does not change. 6 The container volume of the gases is increased

Select the correct answer how does the heat content of the reaction change in the process of photosynthesis when a glucose molecule is formed? ca the value of is negative the value of qis positive the value of a remains constant the value of a decreases the value of equals zero e
