  • Time required to complete 90% of the first order reaction is

  • The half-life of a first order reaction is 30 min and the initial concentration of the reactant is 0.1M. If the initial concentration of reactant is doubled, then the half-life of the reaction will be

  • The rate constant for a first order reaction is 100s1100 \,s^{-1} the time required for completion of 50% of reaction is-

  • The slope of the straight line obtained by plotting rate versus concentration of reactant for a first order reaction is

  • If C0C_0 and C are the concentrations of a reactant initially and after time t then, for a first order reaction

  • When half-life period of a zero order reaction is plotted against concentration of the reactant at constant temperature, the graph obtained is

  • The rate of a reaction between A and B is R=k[A]n×[B]mR = k [A]^n \times [B] ^m On doubling the concentration of A and halving the concentration of B, the ratio of the new rate to the earlier rate of the reaction will be

  • The rate of the first order reaction A \rightarrow products is 0.01 M/s, when reactant concentration is 0.2 M. The rate constant for the reaction will be

  • The rate constant of a reaction

  • For the reaction, Cl2+2I2CI+I2Cl_2 + 2I^- \rightarrow 2CI^-+ I_2 , the initial concentration of II^- was 0.2 mol L10.2 \ mol \ L^{-1} and the concentration after 20 minutes was 0.18 mol L10.18 \ mol \ L^{-1} . Then the rate of formation of I2I_2 in mol L1L^{-1} min1min^{-1} will be
