Question

For the reaction. 2COF_2(g) rightleftharpoons CO_2(g) K_2 = 2.00 at a particular temperature initially contains all three gases in equal concentrations. Which is true of this reaction mixture? Q K. the reaction proceeds toward the reactants The reaction A rightarrow products obeys second order kinetics What in the molar concentration of A remaining after 2 00 minutes if the reaction has a rate constant of 0.0482 M^-1S^-1 and the initial concentration of A is 0.379 M 0 0655 M 0.119 M 0.366 M 8.42 M Determine the reaction order with respect to [A] for the reaction A + B + C rightarrow products 0 2 1.5 2 According to the collision theory far chemical reactions. why do most reaction rates increase as temperature is increased-' At higher temperatures the concentration of reactants increases. the activation energy of the reaction decreases more molecules collide with the necessary energy. more molecules have the proper orientation when they collide. A Chemical reaction is performed at 200 K and at 400 K The reaction has actuation energy of 50 0 kJ mol^-1, At 400 K the me of reaction is the same as the rate at 200 K approximately double the rate at 200 K approximately 200 times the rate at 200 K. A drug is metabolized is a first order reaction with a half life of 4.12 days. If a patient 100.0 mg of this drag. What mass remains after 30.0 days? O.391 mg 0.441 mg 0.643 mg.0.672 mg The reaction HNC(g) rightarrow HCN(g) is first order in [HNC], which plot is correct for this reaction? Consider this reaction mechanism: Step 1 NO_2 (g) + Cl_2 (g) rightarrow_l_1 CINO_2 (g) + Cl(g) (slow) Step 2 NO_2 (g) + Cl(g) rightarrow l_2 ClNO_2 (g) (fast) Overall reaction 2NO_2 (g) + Cl_2 rightarrow 2ClNO_2(g) The overall reaction is_____order with respects to No_2 and__with respect to Cl_2. 2^nd, 2^nd 2^nd, 1^st 1^st 2^nd 1^st 1^st Which energy diagram best illustrates a reaction that is thermodynamically favored but kinetically slow ?

Explanation / Answer

32

If equal concentrations

Q = x*x/(x^2)

Q = 1

since Q < K

then this favours reactants
