Question

Given a general reaction 5x+2y→w+3z, the instantaneous rate of reaction is :

Answer 1

Answer: Rate = −15d[x]dt=−12d[y]dt=d[w]dt=13d[z]dt

For any reaction ax+by→cw+dz, Rate of reaction=−1adxdt=−1bdydt=1cdwdt=1ddzdt

This represents the rate of disappearance of x and y (hence the negative sign) and the rate of appearance of w and z (hence the positive signs).

Therefore, the Rate =−15d[x]dt=−12d[y]dt=d[w]dt=13d[z]dt
