The hydrolysis of ethyl acetate is a reaction of ......... order

$C{{H}_{3}}COOEt+{{H}_{2}}O\xrightarrow{{{H}^{+}}}C{{H}_{3}}COOH+EtOH$

From the following which is a second order reaction

For reaction a $A \to x\;P$, when $[A] = 2.2\,m\,M$, the rate was found to be $2.4\;m\,M\;{s^{ - 1}}$. On reducing concentration of $A$ to half, the rate changes to $0.6\;m\,M\;{s^{ - 1}}$. The order of reaction with respect to $A$ is

A reaction

$2NO + 2H_2 \longrightarrow N_2 + 2H_2O$

has following mechanism

Step $-I$ : $2NO \longrightarrow N_2O_2$

Step $-II$ : $N_2O_2 + H_2 \longrightarrow N_2O + H_2O$

Step $-III$ : $N_2O + H_2 \longrightarrow N_2 + H_2O$

Which of the following substance is a reaction intermediate

Write general equation of reaction and explain - what is order of reaction ? Which is its value ?

The rate of certain reaction depends on concentration according to the equation $\frac{{ - dc}}{{dt}} = \frac{{{K_1}C}}{{1 + {K_2}C}},$ what is the order, when concentration $(c)$ is very-very high
