A zero order reaction \(A\rightarrow B\) .At the end of the of 1h,' A is 75 % reacted. How much of it will be left unreacted at the end of 2 h?

In a zero order reaction , 20% of the reaction complete in 10 s. How much time it will take to complete 50% of the reaction ?

In a zero order reaction half life is 100 sec. After how much time (7)/(8) fraction of reactant will be reacted?

A first order reaction is 20% complete in one hour. At the end of 3 hrs the extent of the reaction is:

A certain substance A is mixed with an equimolar quantity of substance B . At the end of an hour A is 75% reacted. Calculated the time when A is 10% unreacted. (Given order of reaction is zero).

If 30 ml of H_2 and 20 ml of O_2 react to form water, what is left at the end of the reaction ?
