Dear Student,

For first order reaction, k=0
693t12  =0 69310  =0
0693 min-1also, t=2
303kloga0aand a=10% of a0=10100a0or, t=2 3030
0693loga010100a0       =2 3030
0693log10010       = 33 min

Foreign elementary reaction X (g) ---> Y(g) +Z(g). The Half Life period is 10 minutes . in what period of time the concentration of X will be reduced to 10% of original concentration ?
