The reactant concentration of a 1st order reaction at various times 0, t, 2t and 3t are. Co, 2 Co, `a^yCo` and `a^2Co` and `a^zCo` respectively a = constant 0 < a < 1. Establish relation between x, y, z.

The reactant concentrations of a first order reaction at various times, 0 , t , 2t and 3t are c_(0).a^(x)c_(0).a^(y)c_(0) and a^(z)c_(0) , respectively, where 'a' is a constant and 0lealt1 . Establish a relation between x , y and z.

The initial concentration of the reactant in a first order reaction is a . It takes time t for the completion of noth fraction of the reaction. Will it take time 2t for the completion of the same fraction if the initial concentration of the reactant is made twice ?

The rate constant and half-life of a first order reaction at temperature T_(1) " are " k_(1)"min"^(-1) and x_(1) min , respectively and those at temperature T_(2) " are "k_(2) "min"^(-1) and x_(2) min , respectively. If T_(2)gtT_(1) , which is greater , x_(1) " or, " x_(2) ?

Show that , t_(3//4) of a first order reaction is twice the value of t_(1//2) of that reaction.

In a zero -order reaction , initial concentration of the reactant is a and value of the constant is k . If the time required for the completion of the reaction is t and the value of its half-life t_(1//2) then-

Plot a graph of concentration of a reactant at time t, [ (a-x)] against time for a first order reaction .Here a = initial concentration of the reactant an x = change in concentration of the reactant at any time 1 during the reaction.

Initial concentration of the reactant of a first order reaction with a rate constant of 0.01 "min"^(-1) " is " [A]_(0) Concentration of the reactant changes tao [A]_(1) after time t_(1) " and to " [A]_(2) " after time " t_(2). " If " t_(2) -t_(1) is 100 min, then -

For a zero order reaction, the initial concentration of the reactant =[A]_(0) and after time 't' from the initiation of the reaction, the concentration =[A] . What will be the nature of the graph of '[A]' vs 't,

The half-life (t_(1//2)) was determined for a reaction at various initial concentrations of the reaction (a). It was observed that, the value of (axxt_(1//2)) remained constant all through the reaction. The order of the reaction is...........

t_(1//2) of a first order reaction is 15 min . Calculate the time for 80% completion of the reaction . If the initial concentration of the reactant is doubled , calculate the time taken for 80% completion of the reaction Give reasons.
