The rate of a chemical reaction depends on the concentrations of the reactants. let's consider the general reaction between a and b: aa+bb⇌cc+dd the dependence of the reaction rate on the concentration of each reactant is given by the equation called the rate law: rate=k[a]m[b]n where k is a proportionality constant called the rate constant. the exponent m determines the reaction order with respect to a, and n determines the reaction order with respect to b. the overall reaction order equals the sum of the exponents (m+n). for example, if m = 2 and n = 2 then rate = k[a]2 [b]2 and the overall reaction order is 2 + 2 = 4. the reaction orders are experimentally determined and usually not related to the reaction stoichiometric coefficients a and b. the reaction of ethyl bromide with sodium hydroxide, ch3ch2br(aq) + naoh(aq) ch3ch2 oh(aq) + nabr(aq) is first order in ch3ch2br and first order in naoh . if the concentration of ch3ch2br was increased by half and the concentration of naoh was quadrupled, by what factor would the reaction rate increase? express your answer numerically.

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
