1.	For the reaction: `X(g) rarr Y(g)+Z(g)`, the following data were obtained at `30^(@)C`: `{:("Experiment",[X](mol L^(-1)),"Rate" (mol L^(-1) hr^(-1))),(I,0.17,0.05),(II,0.34,0.10),(III,0.68,0.20):}` The rate constant of the above reaction isA. `0.588 hr^(-1)`B. `0.294 hr^(-1)`C. `0.123 hr^(-1)`D. `0.210 hr^(-1)`
Answer» Correct Answer - B In experiments I and II, [X] becomes double and rate is also doubled. Thus it is first, order reaction. `r=k_(f)[X]` `0.05mol L^(-1)hr^(-1)=k_(f)xx0.17molL^(-1)` `:. k_(f)= 0.29hr^(-1)`
