On the basis of thermochemical equations (i), (ii) and(iii) , find out which of the algebric relationships given in options (a) to (d) is correct. (i) C(graphite) `+O_(2)(g) rarr CO_(2)(g), Delta_(r)H = xkJ mol^(-1)` (ii) C(graphite) `+ (1)/(2) O_(2)(g) rarr CO(g), Delta_(r)H= y kJ mol^(-1)` (iii) `CO(g)+(1)/(2)O_(2)(g) rarrCO_(2)(g), Delta_(r)H = z kJ mol^(-1)`A. `z= x+y`B. `x= y-z`C. `x=y+z`D. `y= 2z-x` |
