kindly answer the following question below, choose the best answer. thank u so much
Consider the exothermic combustion of coal. Which of the following could increase the rate of reaction? 57. (a) using smaller pieces of coal (c) lowering the temperature (e) choices (a), (b) and (c) are all correct (b) increasing the concentration of oxygen (d) both (a) and (b) are correct 58. Four of the following factors can affect the forward rate of a chemical reaction. Which one cannot affect this rate? (Note: the question refers to reaction rate, not equilibrium.) (b) concentration of reactants of the forward reaction (a) temperature (c) presence of a catalyst (e) physical state or state of subdivision of solid reactants (d) removal of some of the products of the forward reaction
