Consider the chemical equations shown here. 2H2(g) + O2(g) → 2H2O(g) AH, = -483.6 kJ = 2 =-241.8 kJ/mol
302(g) ► 203(g) AH2 = 284.6 kJ = 2 = 142.3 kJ/mol
What is the overall enthalpy of reaction for the equation shown below?
3H2(g) + O2(g) → 3H20 (g)
kJ

Reaction rate depends on how many molecules are coming into contact with each other with enough energy to react. increasing the temperature of the reactants will increase -

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
