Question

The reaction Is first order in A and second order in B. The overall order of the reaction is _____ A. first. B. second. C. third. D. fourth. E. fifth. In a rate law, the partial orders are never determined by _____ A. the stoichiometric coefficients. B. experiment. C. the initial rates of reactants. D. the trials. E. all of the formers Nitrosyl chloride gas (NOCl) is produced from nitrogen monoxide and chlorine gas according to the following reaction: 2NO(g) + Cl_2(g) rightarrow 2NOCl(g) If the rate of production of NOCl is R(NOCl) (In this case R = delta[]/delta t), what is the rate of loss of NO and Cl_2, respectively? A. -R(NO)= R(NOCl); -R(Cl_2) = R(NOCl) B. -R(NO)= R(NOCl); -R(Cl_2) = 1/2 R(NOCl) C. -R(NO)= 1/2 R(NOCl); -R(Cl_2) = R(NOCl) D. R(NO)= 1/2 R(NOCl); -R(Cl_2) = 1/2 R(NOCl) E. -R(NO)= 2 R(NOCl); -R(Cl_2) = 1/2 R(NOCl) In the combustion of ethane, 2 C_2H_0(g) + 7 O_2(g) rightarrow 4 CO_2(g) + 6 H_2O(g), which product has the greatest rate of appearance? A. C_2H_6 B. O_2 C. CO_2 D. H_2O E. C_2H_6 and O_2 have the same rate of disappearance. Assuming that each of the following graphs has the same concentration and time axes, which has the greatest initial rate of disappearance of reactant? Given the following data, determine the order of the reaction with respect to Cl_2(g). 2NO(g) + Cl_2(g) rightarrow 2 NOCl(g) B. fourth C. third D. second E. first

Explanation / Answer

1) overall order of the reaction is equal to the summation of order with respect to all reactants.

As given in the question, order w.r t. A is one(1st order) and w r.t. B is two (2nd order), thr overall order of the reaction becomes, 1+2=3 (3rd order reaction).
