The minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.
Answer:
A
Explanation:
A linear correlation means the increase in one variable cause an increase in the other variable. In a graph, the linear correlation can be demonstrated by a right-slanted straight diagonal line. Therefore if an increase in carbon dioxide causes a directly proportional increase in global temperatures then the two are correlated.
2 is the correct answer because with 2O2 molecules it balances the chemical equation.
